See Your Site as a Real IPv6-Only Client Does
IPv6 Proxy fetches any website over native IPv6 only — with no IPv4 fallback and no NAT64/464XLAT translation — and forwards the page back to you over your ordinary connection. That makes it a fast, install-free way to confirm whether a site is genuinely reachable over IPv6, exactly as a client with IPv6-only egress (a cloud host or CI runner with no IPv4 address, or any environment where your service must answer natively over IPv6) would experience it. You can also use it the other way around: open IPv6-only websites even if your own ISP or network gives you no IPv6 connectivity at all.
How It Works
1. Enter the address of the website you want to test or open (for example cloudflare.com).
2. Our server resolves the host's AAAA (IPv6) DNS record and connects to it over IPv6 only.
3. The page is fetched over IPv6 and delivered back to you over your normal connection — your own browser needs no IPv6 support at all.
What You Can Do With It
Test your own site's IPv6 readiness: load your pages as a true IPv6-only client would, before committing to a dual-stack or IPv6-only rollout. Mixed-content, hard-coded IPv4 endpoints, and AAAA-less subresources surface immediately.
Check AAAA reachability: confirm a domain not only publishes an AAAA record but is actually served and reachable over IPv6 — not just configured on paper.
Open IPv6-only websites: reach hosts that publish only an AAAA record, even from an IPv4-only network.
No AAAA Record? It Fails on Purpose.
Because this proxy connects over IPv6 only and never falls back to IPv4, a site with no AAAA record — or one that is configured but not actually reachable over IPv6 — will deliberately error out. When you are diagnosing, that error is the answer you came for: positive confirmation the site is not reachable over IPv6, the same way a real IPv6-only client would be left stranded.
IPv6-Enabled Sites to Try
These are reliably dual-stacked and make good "it works" baselines:
google.com — fully dual-stack, a dependable baseline.
cloudflare.com — IPv6 across its global edge.
facebook.com — production IPv6 for years.
www.he.net — Hurricane Electric, an IPv6 backbone pioneer.
www.kame.net — the classic demo: the turtle only dances when you reach it over IPv6.
Tip: use the www. form for these — some don't publish an AAAA record at the bare apex, so the apex itself would "fail by design".
