IPv6 Website Checker

Check if any website supports IPv6. We resolve AAAA records, verify dual-stack reachability and estimate IPv6 latency — perfect for scrapers targeting modern, IPv6-only endpoints.

Enter a domain

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. Knowing your targets accept v6 unlocks 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.
