What IPs to whitelist for KernelCare to work properly?

Issue

The KernelCare cannot download patches or check license, what IPs should be whitelisted for it?

Solution

Generally, KernelCare requires connection to two servers for the proper work:

cln.cloudlinux.com

patches.kernelcare.com  

Their IP addresses may change. So, please double-check their relevancy before whitelisting.

As of December 2025, the list is the following:

100.24.124.173
100.26.107.13
44.201.179.40
23.111.175.209
54.85.28.100
