Frequently asked questions

What are the IP ranges of UptimeRobot?

UptimeRobot publishes 103 IPv4 and 103 IPv6 prefixes (103 IPv4 addresses in total) in its official list at https://uptimerobot.com/inc/files/ips/IPv4andIPv6.txt. This page shows the list as of Oct 1, 2026 and loads the latest copy when it opens.

How often do the UptimeRobot IP ranges change?

Providers add and remove ranges regularly, sometimes several times a week. Do not hard-code the list: load it from its source (or this page's JSON) on a schedule, for example daily.

How do I allow only UptimeRobot in nginx?

Download the nginx format on this page and include it in a location block: one 'allow' line per prefix followed by 'deny all;'. Regenerate the file regularly, because the list changes.

IP geolocation API

Know who is behind any IP

Beyond published lists, the ipbase API tells you the owner, ASN and location of every IP address, and on the Small plan and above its data-center and VPN status, so you can recognise cloud traffic and bots from any provider.
