What record types can PageWarden monitor?

A, AAAA, CNAME, MX, TXT and NS records. You can add an optional expected value so PageWarden verifies the answer, not just that the record resolves.

What is the difference between DNS monitoring and domain monitoring?

DNS monitoring watches whether your records resolve as expected. Domain monitoring watches your registration expiry through WHOIS. They catch different failures.

Bad changes and hijacks

Catch a record that changed under you

A wrong or malicious DNS change can reroute mail or traffic while the site still looks up. Comparing against an expected value catches it early.

This is distinct from domain monitoring, which watches your registration expiry.
