NS Lookup
Look up DNS records.
List a domain's nameservers, or query any common DNS record type.
What are nameservers and DNS records?
Nameservers (NS records) are the authoritative DNS servers responsible for a domain — they hold all of its records and answer lookups for it. This tool lists those nameservers and lets you query other record types too: A and AAAA (IP addresses), MX (mail), TXT (SPF, verification), CNAME (aliases) and SOA (zone details).
