IPv6 Readiness

How ready is your domain for IPv6? We check AAAA records on the apex and www hostnames, every MX host, and every authoritative nameserver, then produce a weighted A–F score.

About the IPv6 Readiness Checker

The IPv6 Readiness Checker grades a domain's IPv6 adoption across the three pillars that actually matter: web (AAAA on the apex and www), mail (AAAA on every MX host), and DNS (AAAA on every authoritative nameserver). Each pillar contributes a weighted portion of a 0–100 score, translated into an A–F grade you can share with stakeholders.

IPv6 adoption is now over 45% globally and 60%+ on mobile networks. Domains still stuck on IPv4-only lose latency (dual-stack users prefer v6 when available), reliability (v6-only networks can't reach you directly), and — increasingly — brand trust from technical audiences. The good news is that most modern hosting providers and CDNs offer IPv6 with a checkbox.

Use IPv6 Readiness to audit your infrastructure, produce a report for compliance reviews, or convince your DNS/hosting vendor to enable AAAA. Pair with Propagation Checker after you turn on v6 to confirm every resolver sees the new records.
