DNS check
Verify your DNS availability and performance with our DNS Checker
With the DNS Checker, you can retrieve your DNS records (such as AAAA records, SOA and TXT) and view their status, all in one overview.
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. The DNS Checker can pull your records into view, together with their status.
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.
That’s a lot of info! Share it
Your DNS records are loaded with sharable information, so share it. Click the button to get a link to your test result. Send the link out to your team or access the test later.
IPv4 and IPv6
The move to IPv6 is on. Nearly half of our 229 checkpoints support IPv6 natively. Check your A record or AAAA record; No matter which IP version you’re running, we’ve got your back.
