What IPs does Uptime use?
Prefer to use User-Agent over IP address allowlisting
We highly recommend you configure your firewall based on our User-Agent since our IPs will change without prior notice. We need to be able to change the IP addresses we make requests from on an ongoing basis to continue scaling our services.
If you do decide to allowlist Better Stack IP addresses, please use a CRON script to refresh the list hourly to ensure you automatically enable new IP addresses as soon as they become available to prevent false incidents.
We rely on a combination of Google DNS and Cloudflare DNS:
8.8.8.8, 8.8.4.4, 1.1.1.1, and 1.0.0.1
