Testing your DNS
Tools to help you find problems with your DNS
There are a number of online tools available that can help you check your DNS and pinpoint problems that might exist. Some examples you may find helpful are:
- MX Toolbox's DNS Check — a simple tool for checking your DNS is set up correctly
- Zonemaster zone check — more comprehensive test
- DNS Checker — a tool to see whether all parts of the Internet have the same DNS for you (checking whether changes have propagated)
- DNSviz — a tool for visualising the status of a DNS zone (especially DNSSEC)
- DNS Bajaj — another visualisation tool
And not directly related to DNS, but helpful nonetheless:
- SSLLabs — test your webserver is set up correctly (checks some DNS things too)
- Internet.NL — test your Internet connection, including your DNS resolver (the other side of your DNS)
