Original GitHub issue: https://github.com/netbirdio/netbird/issues/1483

Describe the problem
I can ping a peer by its IPv4 address but not by its name. When I try, ping says Name or service not known. It works on Windows 11 on a different peer.

To Reproduce
Steps to reproduce the behavior:

Copy a peer numeric ip from https://app.netbird.io/peers
ping <ip>
Copy a peer name from https://app.netbird.io/peers
ping <name>

Expected behavior
Both work the same.

Additional context
Possibly related lines from logfile:
