IPv6 Website Checker

Check if any website supports IPv6. Resolve AAAA records, verify dual-stack reachability and estimate IPv6 latency.

Uses public Google DoH (dns.google) to resolve A and AAAA records.

How it works

Find out if your target is IPv6-ready

Modern endpoints, IoT APIs and CDN edges are increasingly v6-only. We check resolution and reachability so you don't burn proxy budget guessing.

Step 1

DNS lookup

We resolve A and AAAA records via Google's public DoH so you see the same answers a fresh client would.

Step 2

Dual-stack check

We compare both record sets to flag IPv4-only, IPv6-only and properly dual-stacked domains.

Step 3

Latency estimate

We approximate IPv6 reachability latency so you know whether routing your scraper over v6 will hurt throughput.

Cheaper at scale

IPv6 pools cost a fraction of IPv4. If your targets accept v6, you can move to unlimited bandwidth pricing.

Dual-stack aware

Tells you whether to pin v6, pin v4 or let the resolver choose. Important for sticky session jobs.

Fresh data, no cache

Every check hits Google's public resolver, no stale answers from your local DNS or VPN.
