DNS Lookup Tool - Professional Domain Name Resolution

Perform comprehensive DNS lookup queries to resolve domain names to IP addresses. Check A, AAAA, MX, CNAME, TXT, and other DNS records using Google DNS and Cloudflare DNS. Perfect for network troubleshooting and domain analysis.

Comparing answers from two public resolvers is often enough to tell whether a DNS problem is really a delegation issue, a propagation delay, a stale cache path, or simply a misunderstanding about which record type should exist.

When This Is Useful

This page is intended for practical troubleshooting rather than deep authoritative analysis. It is useful when a hostname resolves from one network but not another, when mail delivery depends on MX or TXT correctness, when a service cutover is waiting on public DNS visibility, or when you want a quick sanity check before opening command-line tools on a jump host.

How To Read Resolver Differences

If Google DNS and Cloudflare DNS agree, the result is more likely to reflect what general Internet users will see at that moment. If they differ, that can point to propagation timing, resolver-specific caching, or upstream changes that have not converged yet. A clean result here still does not replace checking the authoritative zone if you control it, but it is a fast way to narrow the problem space.

Things To Watch For

Record type matters. A missing A record does not mean the zone is broken if the service is intentionally IPv6-only, and an unexpected CNAME may be valid if traffic is being handed off through a CDN or verification platform. The ANY type is also not a reliable universal diagnostic because many providers intentionally limit or synthesize responses to it. Treat this page as a public-recursive view, not as the final source of truth.
