Ever since the launch of our DNS scan, we’ve had the warning about mismatched NS records. Many users choose to ignore this, but there’s a pretty good reason we give a big warning whenever those records don’t line up. In this blogpost, we’ll show what can happen with misconfigured NS records.

Back in 2016, we added support for monitoring wildcard DNS records. Wildcard DNS records are used to serve requests for otherwise non-existent domain names.

DNS Check now allows you to specify a wildcard (*) in place of some DNS record values, such as an A record’s IP address to indicate that any value is acceptable, but the record must exist.
The Domain Name System (DNS) is brilliantly designed as a hierarchical structure, ensuring that any single point can fail with the system remaining relatively intact. There are some nuances to this statement, like caching issues that arise from outages, but the overall focus is on uptime. This is why the DNS check is a critical part of your IT uptime monitoring process.
The Domain Name System (DNS) catalog maps text-based URLs to their specifically-numbered host systems. As the phone book or Yellow Pages of the internet, DNS governs the speed with which websites and online resources may be located, so the speed and robustness of your DNS service can have a profound impact on your internet performance overall.
