Free DNS Lookup Tool

Monitor for DNS health around the clock

Multi Browser MonitoringWhat is DNS?

The DNS resolves your domain name to an IP address. It's like a street sign pointing to your website, email, and proxy servers. Without it, your users can't find you.

Website Speed From A to TXT

Monitor your key DNS records such as A, AAAA, SOA, TXT, MX, and root server to know when someone tampers with your DNS, and stop a DNS poisoning in its tracks.

Test worldwideTest worldwide

Just because your DNS works properly on one server, it may not work from all. Our checkpoints catch regional problems before they can spread to the entire DNS network.

Test worldwideCheck serial numbers

The SOA serial number is incremented when a DNS entry changes. Monitoring the serial number catches changes you may not notice if you're only monitoring your A or AAAA records.

Test worldwideKeep email coming

What would happen if your email suddenly stops getting routed to your mail servers? Monitoring your MX record helps you keep your primary communication channels open.

Test worldwideIPv4 and IPv6

The move to IPv6 is on. Nearly half of our 184 checkpoints support IPv6 natively. Check your A record or AAAA record; No matter which IP version you're running, we've got your back.
