Website IPv6 support test
Find out whether a site will open through an IPv6 proxy: we check the AAAA records of the domain and its www version.
With IPv6: 0 · partial: 0 · without IPv6: 0
The first 20 sites were checked, the rest were skipped.

Choose a proxyWhat IPv6 support is and why check it
A website supports IPv6 if its domain has an AAAA record — an address in IPv6 format. An IPv6 proxy goes online from an IPv6 address only, so a site without such a record won't open through it. Check the sites you need before buying to make sure the proxies fit your task.
How to check manually
Open a terminal (on Windows, the Command Prompt) and run one of these commands:
nslookup -type=AAAA example.com
dig AAAA example.com +shortIf the answer has addresses with colons, that is IPv6, and the site supports it. An answer without addresses or "No answer" means there is no AAAA record. nslookup is available on Windows, macOS and Linux, dig on macOS and most Linux distributions.
What the result means
- ✓ IPv6 supported — the domain has an AAAA record: the site should open through an IPv6 proxy.
- ≈ Partial — only the www version or only the version without www has IPv6. Open the site at the address that has IPv6; if the site itself redirects to the address without IPv6, it will not open through an IPv6 proxy.
- ✗ No IPv6 — the domain has IPv4 addresses only. The site won't open through an IPv6 proxy — Dualstack or mobile proxies will work.
- ✗ Domain not found — there is no such name in DNS: check for typos.
Limits of the test
The test looks at the domain's DNS records. A site may load part of a page — the API, images from a CDN, sign-in — from other domains that have no IPv6, and then it will open only partly through an IPv6 proxy. Check those domains too: you can see them in the "Network" tab of the browser's developer tools.
FAQ
How do I know if a website supports IPv6?
Enter the website address in the field above: the test shows whether the domain has an AAAA record and which IPv6 addresses it has. Manually, the nslookup -type=AAAA command with the site's address does the same. If there is no AAAA record, the site works over IPv4 only.
What is an AAAA record?
It is a DNS record that links a domain to an IPv6 address — just as an A record links it to IPv4. Browsers and proxies use it to find where to connect over IPv6. No AAAA record means no access to the site over IPv6.
Why doesn't a site with IPv6 open through an IPv6 proxy?
Most often the page loads part of its data — the API, sign-in, images — from other domains that have no IPv6. A site may also restrict data-center addresses or ask for a captcha. Check the subdomains the site uses and your proxy settings: protocol, login and password.
What if a website doesn't support IPv6?
Such a site needs proxies with IPv4: Dualstack items or mobile proxies. It won't open through an IPv6 proxy — that is not a proxy fault, and there is no replacement for that reason.
Do Google, YouTube and Instagram support IPv6?
Yes, Google, YouTube, Facebook and Instagram answer over IPv6. But support can differ between individual subdomains and services and change over time, so it is best to check the addresses you need here before buying.
