Monitor DNS changes on Cloudflare
One of the most widely used authoritative DNS providers, often paired with its CDN and proxy.
Catch Cloudflare DNS changes before they cause problems
A changed A record, a swapped nameserver, or a removed TXT record can take a site down or break email — often without anyone noticing until it’s a problem. Domnr periodically snapshots your domain’s DNS and alerts you when records change, whether the change was intentional or not.
What Domnr watches
- Record changes — A, AAAA, MX, TXT, NS, CNAME, and SOA, compared against the last snapshot.
- Nameserver moves — know immediately if a domain stops pointing at Cloudflare.
- SSL & uptime — paired with certificate and uptime monitoring, so DNS isn’t the only thing you’re watching.
