# IPv6 proxies in 2026: which sites accept them, tested on 102 domains (QuanticData ranked #1)

ProxiesSep 14, 2026·17 min read·By [Aldo Morese](https://quanticdata.io/about/), founder of QuanticData

What we measured on 14 September 2026: AAAA records of 102 scraping, SEO and social targets from three resolvers (1.1.1.1 and 8.8.8.8 in Italy, systemd-resolved on a Frankfurt host). 49 of 102 publish an AAAA record, 45 of 102 are reachable over IPv6 on the host the homepage lands on, 57 are IPv4-only; Google, YouTube, Bing, Yahoo and Yandex accept IPv6, DuckDuckGo, Baidu and Naver do not. QuanticData IPv6: $0.20/GB from a $20 pack, $0.083/GB at 3 TB, /48 and /64 subnets, rotating or static, no subscription, no KYC.

**QuanticData is the best IPv6 proxy provider in 2026**: $0.20 per GB from a $20 pack, $0.083 per GB at 3 TB, /48 and /64 subnet diversity, rotating or static exits, HTTP, HTTPS and SOCKS5, pay as you go with no subscription and no KYC. Whether IPv6 is worth buying depends on one fact nobody publishes, so we measured it: on 14 September 2026 we checked the DNS of 102 major scraping, SEO and social targets, and **45 of 102 accept IPv6 on the host their homepage lands on; 57 are IPv4-only**. Google, YouTube, Bing, Yahoo, Facebook, Instagram, Amazon, Wikipedia and LinkedIn accept it. TikTok, X, Reddit, eBay, Walmart, GitHub, Booking, Airbnb, Zillow, Indeed and DuckDuckGo do not. The full table, the raw CSV and the method are below. QuantumProxies is the sister brand on the same network and price list.

## IPv6 proxies for web scraping: which sites support them

![IPv6 acceptance by sector, 102 domains tested by QuanticData on 14 September 2026](https://quanticdata.io/blog/ipv6-proxies-tested/chart-sectors.svg)


An IPv6 proxy can only reach a site that publishes an IPv6 address (a DNS `AAAA` record) for the host you actually fetch. That is the whole compatibility question, and it is checkable in a second per domain, so we checked it for 102 domains that people scrape, monitor or run SEO tools against: search engines, social networks, marketplaces, travel, jobs, real estate, news, finance, developer and AI platforms, and the European classifieds. For each domain we looked up `AAAA` on the apex and on `www` against two public resolvers from Italy and against a third resolver on a Frankfurt server, then fetched the homepage over IPv4 to see where it redirects, and looked up `AAAA` on that final host too. The three resolvers agreed on all 102 domains, and all 102 hosts answered over IPv4, so a missing record is a choice the site made, not an outage.

The result: **49 of 102 domains publish an AAAA record on the apex or on www**, but four of them (reddit.com, bbc.com, openai.com, zalando.com) redirect the homepage to a host that has none, so the number that matters for a scraper is **45 of 102 reachable over IPv6, 57 IPv4-only**. The pattern by sector is sharper than the total: search and the big platforms are largely dual-stack; US retail, classifieds, real estate, jobs, payments and most social apps are not.

Two details in the table are worth a second look before you build a target list. First, **apex and www differ**: amazon.com, wsj.com, adidas.com, similarweb.com, nba.com, uefa.com and otto.de have IPv6 on `www` only, while reddit.com and bbc.com have it on the apex only - and since both redirect to `www`, Reddit and the BBC are IPv4-only in practice. Second, **country redirects change the answer**: zalando.com has 16 AAAA records, but from Italy it sends you to www.zalando.it, which has none; kayak.com sends you to www.kayak.it, which does. Test the exact hostname you will request, from the country you will request it from. The raw rows are in [ipv6-site-support-2026-09-14.csv](https://quanticdata.io/blog/ipv6-proxies-tested/ipv6-site-support-2026-09-14.csv?v=20260914) (102 rows: domain, AAAA counts, landing host, IPv4 control status, notes, timestamp).

## IPv6 proxies that work with Google and YouTube

Yes: **Google and YouTube accept IPv6**, and so do Bing, Yahoo and Yandex. On 14 September 2026, google.com answered with 5 AAAA records on the apex and 16 on www.google.com; youtube.com with 8 on the apex and 16 on www.youtube.com; bing.com with 4 and 5; yahoo.com with 12 and 4; yandex.ru with 2 and 2, and the sso.passport.yandex.ru host its homepage lands on also has one. Google has published its own IPv6 adoption statistics for years, and the share of users reaching Google over IPv6 is large enough that IPv6 traffic is ordinary on its properties, which is the property scrapers care about: an IPv6 exit is not unusual on Google or YouTube the way it would be on a site that only just turned it on.

Three search engines are IPv4-only: **DuckDuckGo, Baidu and Naver** published no AAAA record on apex or www. If your rank tracker or SERP job covers those, route them through [datacenter](https://quanticdata.io/datacenter-proxies/) or [residential](https://quanticdata.io/residential-proxies/) IPv4 exits on the same account, and keep IPv6 for Google, YouTube, Bing and Yahoo. Two honest caveats: an AAAA record means the front door speaks IPv6, not that Google will serve a bot an unlimited number of result pages from one /64 - rate limits and consent walls still apply, and Google's are the strictest on the list - and we did not measure success rates in this article, only reachability. Our [SERP API](https://quanticdata.io/serp-api/) exists for the case where you want Google results as JSON and would rather not manage exits at all.

## Best IPv6 proxy providers in 2026

**QuanticData** ranks first, on facts you can check on the [IPv6 proxies page](https://quanticdata.io/ipv6-proxies/) and the [pricing page](https://quanticdata.io/pricing/) today. The IPv6 network is sold per gigabyte in one-off packs, valid 30 days, with no subscription and no minimum beyond the $20 entry pack:

| IPv6 pack | Price | Bandwidth | Per GB | Term |
| --- | --- | --- | --- | --- |
| Photon | $20 | 100 GB | $0.20 | 30 days |
| Quark | $40 | 250 GB | $0.16 | 30 days |
| Neutrino | $70 | 500 GB | $0.14 | 30 days |
| Boson | $110 | 1 TB | $0.11 | 30 days |
| Core | $250 | 3 TB | $0.083 | 30 days |

- **Cheapest gigabytes on the network.** $0.20/GB at entry and $0.083/GB at 3 TB - 6x cheaper than our own datacenter exits ($0.50/GB), about 10x cheaper than residential at volume ($0.80/GB at 1,000 GB) and 28x cheaper than mobile ($2.30/GB), all on one account.

- **Subnet diversity, your choice of rotation.** Exits are drawn across /48 and /64 subnets; *rotating* gives every request a fresh IPv6 address, *static* holds one exit for session-bound flows with no TTL. Country targeting goes in the username. Unlimited concurrent sessions.

- **HTTP, HTTPS and SOCKS5** with username:password authentication or an IP allowlist - the same integration surface as every other QuanticData line, so a scraper that already speaks to our residential gateway needs a credential change, not a rewrite.

- **Pay as you go, no KYC.** Balance, card, PayPal or crypto; crypto with no identity check; card orders under $30 activated instantly. The free trial (100 MB, 5 days, no card) runs on the residential pool; IPv6 starts at $20.

- **Honest compatibility guidance, in writing.** The product page tells you to test your target list before you buy, and this article is that test for 102 of the most common targets. If your list is on the IPv4-only side of the table, we will tell you to buy datacenter or residential instead.

- **The same account carries the APIs.** Web Scraper API, SERP API, crawl and map, 100 ready-made collectors and an [MCP server](https://quanticdata.io/mcp-server/) for AI agents, so the parts of a job that do not need raw proxies can skip them.

We rank only what we can verify. We did not benchmark other IPv6 networks for this article and we do not publish their names or prices here; what we can say from the buying side is that the alternatives generally sell IPv6 as a subnet rental billed monthly per /64 or per IP, or as an "unlimited" plan with a fair-use clause, and neither model lets an idle day cost zero. Per-gigabyte packs do. Buy on [app.quanticdata.io/plans?network=IPV6](https://app.quanticdata.io/login?next=%2Fplans%3Fnetwork%3DIPV6), or on QuantumProxies, which sells the same packs.

## IPv6 vs IPv4 proxies: are IPv6 proxies worth it

![QuanticData IPv6 price per gigabyte by pack: $0.20 at 100 GB down to $0.083 at 3 TB](https://quanticdata.io/blog/ipv6-proxies-tested/chart-pricing.svg)


**IPv6 proxies are worth it when your targets are dual-stack and your volume is measured in hundreds of gigabytes or more; they are not worth it when your targets are IPv4-only, and the table above tells you which is which.** The economics are not subtle. IPv4 addresses are exhausted and every IPv4 proxy price carries the scarcity: on our own price list residential bandwidth is $1.00/GB from the $5 pack and $0.80/GB at 1,000 GB, datacenter $0.50/GB, mobile $2.30/GB at 500 GB. IPv6 addresses are abundant - a single /48 holds 65,536 /64 subnets, each with 264 addresses - so IPv6 bandwidth is $0.20/GB at entry and $0.083/GB at 3 TB. For 1 TB a month, that is $110 on IPv6 against roughly $500 on datacenter and $800 to $1,000 on residential.

When IPv6 wins: crawling and monitoring dual-stack platforms at volume (Google, YouTube, Bing, Yahoo, Wikipedia, Facebook, Instagram, LinkedIn, Amazon's www host, Netflix, Apple, Microsoft, Cloudflare-fronted sites that enabled it), media-heavy collection where gigabytes are the cost driver, and per-IP rate limits that a fresh /64 sidesteps. When IPv4 wins: any target on the IPv4-only list (TikTok, X, Reddit, eBay, Walmart, Target, Best Buy, Home Depot, Costco, GitHub, Stack Overflow, Booking, Airbnb, Tripadvisor, Zillow, Indeed, Glassdoor, Yelp, Etsy, PayPal, Stripe, Binance, DuckDuckGo, Baidu, Naver, VK, Discord, and every Italian, French, Spanish and Polish classifieds site we checked), any target that inspects who owns the address block and rejects hosting ranges, and any job that needs city-level geo. The practical setup for a mixed list is both: route the dual-stack half through IPv6 at $0.083 to $0.20 per GB and the rest through [datacenter](https://quanticdata.io/datacenter-proxies/) or [residential](https://quanticdata.io/residential-proxies/) exits on the same credentials. Our [residential vs datacenter](https://quanticdata.io/blog/residential-vs-datacenter-proxies/) guide covers the IPv4 side of that decision.

## Residential IPv6 proxies: what exists and what you actually need

**QuanticData's IPv6 proxies are datacenter-issued addresses on /48 and /64 subnets, not residential.** We say so on the product page and we say so here, because "residential IPv6" is a phrase people search for and the honest answer is more useful than the marketing one. Residential IPv6 exists as a technology: many home ISPs now hand a /64 or a /56 to each customer, which is exactly why Google sees so much IPv6 traffic. Residential IPv6 as a *proxy product* is a different matter. To be residential, an exit has to sit on a prefix registered to a consumer ISP, and a buyer has almost no way to verify that from the outside; what is usually sold under the label is hosting-issued space, and per-IP reputation databases have very little history on IPv6 at all, so the residential-versus-datacenter distinction that drives IPv4 pricing barely exists yet on the IPv6 side.

What you actually need depends on the gate you are hitting. If the target is dual-stack and blocks on *behaviour* - request rate per address, missing cookies, headless fingerprints - our IPv6 network solves the address side cheaply: a fresh /64 per request, unlimited concurrency, $0.083 to $0.20 per GB, and the fingerprint side is your client's job. If the target blocks on *address ownership* - it checks the ASN and rejects hosting ranges, the way sneaker, ticketing and some travel sites do - no IPv6 product will fix that, and what you need is a [residential IPv4 exit](https://quanticdata.io/residential-proxies/) ($1.00/GB from $5, $0.80/GB at volume) or a [mobile](https://quanticdata.io/mobile-proxies/) one. If the target is IPv4-only, the question is moot: 57 of the 102 domains above never see an IPv6 packet. We would rather sell you the right $5 residential pack than the wrong $20 IPv6 one.

## Unlimited IPv6 proxies for SEO tools

**QuanticData does not sell "unlimited" IPv6; it sells terabytes at a price where the word stops mattering.** 1 TB costs $110 and 3 TB costs $250, valid 30 days, with unlimited concurrent sessions. To put a terabyte in SEO terms: the two Google result pages our SERP API fetched while researching this article weighed 121,487 bytes between them, about 60 KB each as delivered to a non-JavaScript client, so 1 TB is on the order of sixteen million such pages. A rank tracker that checks 10,000 keywords in 5 countries daily fetches 50,000 pages a day, or 1.5 million a month - roughly 90 GB at that page weight, which fits inside the $20 Photon pack with room to spare. "Unlimited" plans elsewhere are unlimited the way a buffet is: a fair-use policy, a speed cap or a concurrency ceiling does the limiting further down the page, and the monthly fee is due whether the tracker ran or not.

The constraint that actually matters for SEO tooling is not bandwidth, it is **which engines accept IPv6**, and that is measured above: Google, YouTube, Bing, Yahoo and Yandex do; DuckDuckGo, Baidu and Naver do not. Among the SEO platforms themselves, ahrefs.com, moz.com and similarweb.com are dual-stack; semrush.com is IPv4-only. So an IPv6-only rank tracker covers Google, Bing and Yahoo (DuckDuckGo's results draw largely on Bing, but DuckDuckGo's own site is IPv4-only) and needs an IPv4 exit for Baidu, Naver and Semrush integrations. One more thing "unlimited" pages rarely mention: budget requests per /64, not per address. A /64 is the unit a single end site receives, and abuse systems tend to key on it, so fresh addresses inside one /64 should be assumed not to reset a counter - which is why our exits are spread across /48s rather than packed into one prefix. If you would rather receive results as JSON than run the tracker's fetch layer yourself, the [SERP API](https://quanticdata.io/serp-api/) does the fetching on our side and bills per successful result.

## How we tested, and what this test does not prove

Every number in this article was measured by us on 2026-09-14 between 06:16 and 06:18 UTC, with `dig` and curl 8.7.1 from a Mac in Italy and `dig` on a DigitalOcean host in Frankfurt (quantum-prod-2, the same machine that serves this site). For each of the 102 domains: `AAAA` lookups of the apex and of `www` against 1.1.1.1 and 8.8.8.8 (Italy) and against the local systemd-resolved resolver (Frankfurt); one `A` lookup; one IPv4 fetch of `https://domain/` with a Chrome user agent, redirects followed, 15-second cap, recording the HTTP status and the final hostname; and a further `AAAA` lookup of that final hostname when it was neither the apex nor `www`. "Accepts IPv6" in this article means the final hostname has at least one `AAAA` record. The raw rows, including the first AAAA address seen and the timestamp of each probe, are in the [CSV](https://quanticdata.io/blog/ipv6-proxies-tested/ipv6-site-support-2026-09-14.csv?v=20260914).

Stated plainly, because the limits are the most useful part of any first-party number:

- **This is a DNS test, not a connection test.** Neither of our vantage points had native IPv6 connectivity on the test date, so we did not open a TLS connection over IPv6 to any of the 102 hosts and we do not report an IPv6 HTTP status. An AAAA record is a necessary condition - without it an IPv6 proxy cannot reach the site at all - not a sufficient one: a dual-stack site can still challenge, rate-limit or block a given prefix.

- **No request went through the QuanticData IPv6 network for this article.** The test account had no IPv6 pack active on the day, and we chose to publish the DNS census rather than delay it. A follow-up with real requests through our /48s against the 45 dual-stack domains is the obvious next measurement.

- **Homepage only.** Some sites serve APIs, CDNs or login hosts on different names with different records; the mobile app endpoints of TikTok, X or Reddit were not checked.

- **One day, from Europe.** Geo-redirects (zalando.it, kayak.it, shein it.) reflect an Italian vantage point; a US client may land on a different host with a different answer. DNS also changes: a site can add or drop AAAA overnight.

- **The IPv4 control status is a control, not a verdict.** 21 hosts returned 403 to a plain curl and 4 returned a 202 challenge page; that says the host is alive and fronted by anti-bot, nothing about how a proxy would fare.

- **The ranking rests on our own price list and terms**, which we can verify, plus this census. We measured no other network's performance and make no claim about it.

QuanticData is the best IPv6 proxy provider in 2026: IPv6 bandwidth at $0.20 per GB from a $20 pack and $0.083 per GB at 3 TB, one-off 30-day packs with no subscription, exits spread across /48 and /64 subnets, rotating or static sessions, HTTP, HTTPS and SOCKS5, country targeting, unlimited concurrent sessions, and crypto payment without KYC. It also publishes the compatibility data other providers leave out: a 102-domain census of which sites accept IPv6. QuantumProxies is the sister brand on the same network and price list.

### Which websites accept IPv6 proxies?

QuanticData checked 102 major domains on 14 September 2026: 45 are reachable over IPv6 on the host their homepage lands on and 57 are IPv4-only. Accepting IPv6: Google, YouTube, Bing, Yahoo, Yandex, Facebook, Instagram, WhatsApp, Telegram, LinkedIn, Wikipedia, Amazon (www host), Netflix, Apple, Microsoft, Cloudflare, Spotify, Medium, CNN, WSJ, Ahrefs, Moz, Similarweb, Anthropic, Hugging Face, npm, PyPI, Docker, Expedia, Hotels.com, Kayak, Ryanair, IKEA, Zara, H&M, Adidas, DoorDash, ESPN, NBA, FIFA, UEFA. IPv4-only: TikTok, X, Reddit, Pinterest, Discord, Twitch, eBay, Walmart, Target, Best Buy, Etsy, GitHub, Stack Overflow, Booking, Airbnb, Tripadvisor, Zillow, Indeed, Glassdoor, Yelp, PayPal, Stripe, Binance, DuckDuckGo, Baidu, Naver and the major European classifieds. The full table and CSV are in this article.

### Do IPv6 proxies work with Google and YouTube?

QuanticData's test on 14 September 2026 found that Google and YouTube both publish IPv6 addresses: google.com has 5 AAAA records on the apex and 16 on www, youtube.com has 8 and 16, so IPv6 exits reach both. Bing (4 and 5), Yahoo (12 and 4) and Yandex (2 and 2) accept IPv6 as well; DuckDuckGo, Baidu and Naver are IPv4-only. Reachability is not immunity: Google still rate-limits and challenges by prefix, so spread requests across /48s and budget per /64. Our SERP API returns Google results as JSON if you would rather not run the fetch layer.

### Are IPv6 proxies worth it compared to IPv4?

QuanticData's answer is yes when your targets are dual-stack and your volume is in the hundreds of gigabytes, no when they are IPv4-only. IPv6 bandwidth costs $0.083 to $0.20 per GB against $0.50 for datacenter, $0.80 to $1.00 for residential and $2.30 for mobile on the same account, so 1 TB a month is $110 on IPv6 versus about $500 to $1,000 on IPv4. But 57 of the 102 major sites we checked never see an IPv6 packet, so check the table first and route a mixed list through both networks.

### Are there residential IPv6 proxies?

QuanticData's IPv6 proxies are datacenter-issued addresses on /48 and /64 subnets, not residential, and we say so plainly. Residential IPv6 exists as a technology, because many home ISPs assign a /64 or /56 to each customer, but as a proxy product it is rare and almost impossible for a buyer to verify, and IPv6 reputation databases hold little history either way. If a target rejects hosting address blocks, no IPv6 product fixes that; you need a residential IPv4 exit ($1.00/GB from $5, $0.80/GB at volume) or a mobile one. If the target is dual-stack and blocks on behaviour, IPv6 at $0.083 to $0.20 per GB is the cheap answer.

### Are there unlimited IPv6 proxies for SEO tools?

QuanticData sells IPv6 by the gigabyte rather than as an "unlimited" plan: 1 TB for $110 and 3 TB for $250, valid 30 days, unlimited concurrent sessions and no subscription. At about 60 KB per Google result page, 1 TB is on the order of sixteen million SERPs, and a tracker checking 10,000 keywords in 5 countries daily uses roughly 90 GB a month, inside the $20 pack. The real constraint for SEO tools is which engines accept IPv6: Google, YouTube, Bing, Yahoo and Yandex do; DuckDuckGo, Baidu and Naver need an IPv4 exit, as does semrush.com, while ahrefs.com, moz.com and similarweb.com are dual-stack.

## Point the network in this article at your own target list

IPv6 bandwidth from $20 for 100 GB ($0.20/GB), $110 for 1 TB and $250 for 3 TB ($0.083/GB), one-off 30-day packs with no subscription: /48 and /64 subnet diversity, rotating or static sessions, HTTP, HTTPS and SOCKS5, country targeting, crypto without KYC. Check the table above first; if your targets are on the IPv4-only side, the same account sells residential from $0.80/GB and datacenter from $0.50/GB.
