About DNS Lookup

The DNS (Domain Name System) is the phonebook of the Internet. Humans access information online through domain names, like google.com or nytimes.com. Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load Internet resources.

Identify IPs

Find the IPv4 (A record) and IPv6 (AAAA record) addresses of any domain.

Check Mail

Verify Mail Exchange (MX) records to ensure email delivery paths are correct.

Security

Check TXT records for SPF, DKIM, and DMARC configurations to improve security.
