DNS Lookup
Query nameservers worldwide for A, AAAA, MX, TXT, CNAME, NS, SOA, and PTR records with TTLs and status details.
Understanding Essential DNS Record Types
The Domain Name System (DNS) translates human-readable domain names into IP addresses and routes internet traffic to the correct mail and web servers.
MX (Mail Exchange)
Specifies the mail servers responsible for receiving email on behalf of your domain name, ordered by priority numbers.
TXT (Text Records)
Holds machine-readable text used for domain verification, SPF authorization, DKIM public keys, and DMARC policies.
A & AAAA Records
A records map hostnames to 32-bit IPv4 addresses, while AAAA records map to 128-bit IPv6 addresses.
