Is your domain ready for the IPv6 internet?

Our 11-point readiness audit checks your nameservers, website and mail servers for IPv6. Seven checks run live in your browser right now; the four connectivity probes are part of our full audit.

Input / DomainLive DNS

Live checks use secure DNS-over-HTTPS (Cloudflare, Google DNS fallback) directly from your browser. Nothing is sent to Xaccel or stored.

Server-side checks Tests 2 · 5 · 6 · 8

These four tests open real network connections over IPv6 — something a browser sandbox can't do. They're not guesses: we simply don't run them here. Available in the full audit — book a free assessment.

  • Test 2 — Nameserver IPv6 connectivity — queries each IPv6 nameserver directly and confirms it answers authoritatively over IPv6.
  • Test 5 — Web server IPv6 connectivity (HTTP) — fetches your site over IPv6 on port 80 and records the status code.
  • Test 6 — Secure web server IPv6 connectivity (HTTPS) — same, with TLS on port 443, catching certificate and handshake issues.
  • Test 8 — Mail server IPv6 connectivity — connects to each MX over IPv6 (ports 25/587/465) and reads the SMTP banner.

Enter a domain and we'll run the 7 DNS-verifiable tests of the 11-point audit live: IPv6 addresses for your nameservers, web server, bare domain and mail servers, reverse DNS for mail IPv6, SPF IPv6 references, and the full delegation trace.

WHY / IPV6 MATTERS

IPv4 ran out of room. Your customers haven't.

Over 40% of internet users now reach you over IPv6 first — on mobile networks, it's the majority. Being IPv6-ready isn't future-proofing; it's present-tense reachability.

::1

Reach every visitor

Mobile carriers and many ISPs are IPv6-only behind translation layers. Without AAAA records, those users take the slow, fragile path to you — or none at all.

RTT

Faster connections

IPv6 avoids NAT translation and carrier-grade workarounds. Major platforms report measurably lower latency over IPv6 — speed your site gets for free.

2040

Ready for what's next

Cloud providers now charge extra for scarce IPv4 addresses, and some new services ship IPv6-first. Readiness today avoids an emergency migration tomorrow.
