💡 About DNS Lookup
DNS (Domain Name System) is the phonebook of the internet. It translates human-readable domain names like "google.com" into IP addresses that computers use to communicate. This tool lets you look up various DNS records for any domain.
Common DNS Record Types:
A Record: Maps domain to IPv4 address
AAAA Record: Maps domain to IPv6 address
MX Record: Mail server records
TXT Record: Text records (SPF, DKIM, etc.)
NS Record: Nameserver records
CNAME Record: Canonical name (alias)
Once you find the IP addresses from DNS records, you can use our IP Address Lookup tool to get detailed geolocation and ISP information for each address.
