NSLookup Online - Name Server lookup.

NSLOOKUP displays information about the Domain Name System (DNS [RFC1034, RFC1035]) and maps domain names to IP addresses or vice versa. This tool lets you query a specific name server or our default resolver, verify delegation chains, and troubleshoot records such as PTR for reverse lookups.

Domain name

Domain name to query, e.g. example.com

Server (optional)

Name or IP of the server to query.

Record type

Choose a specific record or use ANY for all records.

How NSLookup helps

NSLookup is a trusted CLI utility that this page wraps. It surfaces DNS answers that every server sees so you can verify delegations, TTLs, and server availability before rolling out DNS changes.
