strange behaviour when one of my servers boots up

[s_m_m]

Hi lovely forum people! I've been using pfSense for the past four months or so and recently noticed a weird pattern of behaviour when I boot up one of my servers. The machine runs Proxmox and usually there should be a ip address assigned to the web ui and two virtual machines, one True NAS, the other (which I start manually) windows.

in the following image you can see a series of two minute reservations being handed out sequentially

I expect .217 and .219 (windows and true NAS respectively) and there is a static ip for Proxmox admin but am baffled where these other ips are being handed out to (it's just the two VMs running.

Should I be worried? Is this a glitch? I will note that this only happens when this machine boots and it seems to have started happening after I installed the Tailscale plugin (currently disabled).

Any advice would be very much appreciated!
