A DNS lookup using our tools can give you insights on the records associated with the queried domain name. It returns the A record (IP address), mail server (MX records), the nameserver (NS records), SPF (TXT) records, and other Domain Name System (DNS) records.
Our DNS database is one of the most exhaustive in the world. We have tracked more than 2.3 billion domains and subdomains, and so our database contains over 142 million mail exchanger (MX) records and 196+ million NS records. More records are added as we update the database every day. We also cover 99.5% of all IP addresses in use.
We cover 2,864+ top-level domains (TLDs) among which are generic (gTLDs) and country-code (ccTLDs).
