Describe the bug:
The cluster contains 3 physical servers in one datacenter each with Internet-accessible IP addresses

In the absence of availability of one of the machines for a short period of time, the second assigns itself its IP address.

As a result, there is a situation with a doubling of IP addresses and one of the machines becomes inaccessible from the Internet. After reconnecting the network on it, the IP address of the machine that "took the IP" is removed and the cluster resumes normal operation.

This is unexpected behavior and i can't find any docs about it

In the absence of availability of one of the machines for a short period of time, the second assigns itself its IP address.

I have no idea what would cause this, nor have I seen anyone mention this in the past. Do you perhaps have something else deployed to the nodes that's managing addresses or virtual IPs?

[brandond]

Can you provide rke2-server logs and/or kubectl get node -o yaml output when the machine with the "doubled IP" is present in the cluster?
