Monitoring IP ranges
When your servers, databases or internal APIs live behind a firewall, our monitors can't reach them — until you let us in. Add these IPs to your allowlist and checks run against your private infrastructure just like they do for anything public. The list stays stable, and every address is provably ours (that's what /bot is for), so you're not opening a hole for some mystery range.
Grab the list
Static — but re-fetch when you automate
These addresses don't change on a whim, but we add regions over time. If you allowlist programmatically, pull /ips.json (or the .txt files) on a schedule rather than hard-coding, so new locations are picked up automatically.
Every location, by region
