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.
Enter the required value in the input field above (domain, IP, URL, or text depending on the tool).
