Uses public Google DoH (dns.google) to resolve A and AAAA records.
Modern endpoints, IoT APIs and CDN edges are increasingly v6-only. We check resolution and reachability so you don't burn proxy budget guessing.
We resolve A and AAAA records via Google's public DoH so you see the same answers a fresh client would.
We compare both record sets to flag IPv4-only, IPv6-only and properly dual-stacked domains.
We approximate IPv6 reachability latency so you know whether routing your scraper over v6 will hurt throughput.
IPv6 pools cost a fraction of IPv4. If your targets accept v6, you can move to unlimited bandwidth pricing.
Tells you whether to pin v6, pin v4 or let the resolver choose. Important for sticky session jobs.
Every check hits Google's public resolver, no stale answers from your local DNS or VPN.
