DNS Lookup

This is a free DNS lookup tool, meant to make it easy to perform A record lookups, AAAA IPv6 record lookups, CNAME record lookups, MX record lookups, TXT record lookups, and NS record lookups. Since SPF records are stored as TXT type, it can also be used for verifying which IPs are allowed to send mail for a specific domain.

Your lookup will not be stored.
