What is a DNS lookup?
DNS Lookup shows public information (DNS records) for a given domain including A records, email (MX) records, CNAME records, text (TXT) records and nameserver (NS) records. Our lookup supports both IPv4, IPv6, and domain name input.
How does it work?
Our DNS lookup relies on Go's standard library to make DNS requests. For more information please view the official nslookup wikipedia page.
