DNS monitoring

One DNS edit can move your website or your email somewhere else. FastPing watches the records you choose and reports every change.

Check details

FastPing asks public resolvers (Cloudflare, Google or Quad9) for one record type of your name.
The first answer becomes the reference. Every later difference sends a change alert with the new values.
Missing records, resolver errors and a missing expected value turn the monitor down.

Nine record types
A, AAAA, CNAME, MX, NS, TXT, SOA, CAA and SRV.
Change detection
Any added, removed or modified answer is reported.
Expected values
Require an answer to contain a given text, such as your mail host.

Create a DNS records monitor with the hostname and the record type. Optionally, set the text an answer must contain. Attach alert channels and save.

If your question is not here, write to us. We reply by email, usually within one business day.

Will a CDN that rotates IP addresses cause alerts?

Yes, every rotation is a change. For such names, monitor the CNAME or NS records, or require a value that does not rotate.

How do I notice any change to my zone?

Monitor the SOA record: its serial number changes with every edit of the zone.

Can I compare the answers of different resolvers?

The free DNS propagation checker compares the answers of 8 public resolvers at once.

3 monitors, checks every 5 minutes and 1 status page. No payment details needed.
