Enter a domain name to look up its records including A, AAAA, MX, TXT, NS, and CNAME records.
A DNS lookup becomes much more useful when you read it as a troubleshooting workflow rather than just a record dump. Start by confirming the record type that matches the problem. If a website is unreachable, compare and responses to make sure the domain resolves to the expected IPv4 or IPv6 address. If mail is failing, focus on records, then review values for SPF, DKIM, or verification entries that can affect delivery and reputation.
Another common mistake is treating one resolver response as the full truth. Cached answers, regional routing, CDN behavior, and stale local resolvers can make results appear inconsistent. That is where TTL helps: a short cache lifetime usually means answers can change quickly, while a longer TTL suggests a resolver may continue serving older data until the cache expires. When you are mid-migration or waiting for propagation, record type, TTL, and nameserver alignment matter more than a single lookup snapshot.
Misconfigurations often show up as subtle mismatches: an MX record pointing to a hostname with no A record, a CNAME chain where the target does not resolve, or authoritative name servers that do not match the registrar delegation. In those cases, combine this tool with reverse DNS, WHOIS or RDAP, and hostname resolution checks so you can distinguish a genuine configuration error from a temporary cache delay or provider-side routing choice.
