Original GitHub issue: https://github.com/netbirdio/netbird/issues/4977

The problem:

only two clients are installed (proxmox CT and Windows 11) on two different machines, and the NetBird server is hosted at my home. This is the number of queries made in 24 hours, which is really disappointing. This issue may have been introduced a long time ago. One client is installed at a remote location, and that ISP banned my NetBird server’s IP and said they had been monitoring it for quite a long time.

In the image I provided, you can see the exact NetBird client query name on my Pi-hole DNS server and these are coming from windows pc and proxmox CT.
