Free DNS Lookup Tool
Monitor for DNS health around the clock
What 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.
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 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.
Check 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.
Keep 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.
IPv4 and IPv6
The move to IPv6 is on. Nearly half of our 201 checkpoints support IPv6 natively. Check your A record or AAAA record; No matter which IP version you're running, we've got your back.
