What is DNS Lookup?

DNS (Domain Name System) translates domain names into IP addresses and stores various records that control how a domain behaves. A DNS lookup queries these records from authoritative or recursive DNS servers.

Common record types: A maps a domain to an IPv4 address, AAAA to IPv6, MX defines mail servers, TXT stores verification and policy data (SPF, DKIM, DMARC), NS lists nameservers, SOA provides zone authority info, and CAA specifies allowed certificate authorities.

DNS queries are sent to Google (8.8.8.8), Cloudflare (1.1.1.1), Quad9, or OpenDNS. Your query is sent to our server which performs the lookup. We do not log queries.
