DNS monitors

Make sure a DNS record still returns what you expect.

Last reviewed November 11, 2026

A DNS monitor looks up one record for a domain and compares the answer with the values you expect. If a value is missing, an incident opens and the answer we found is in the cause.

Supported record types are A, AAAA, CNAME, MX, NS, TXT, SOA and SRV. Every value you list must be present in the answer. Case, trailing dots and quotes around TXT values are ignored when comparing.
