IP Sharing/Balancing/Rotation question (I think?)

[averagewren]

Hey all, just wanted to start by saying I absolutely adore this client and have been using it for years.

So im running into an issue where I get a different ip address with each container that is connected to gluetun and when I run a wget command to check the ip address I get a different one each time even though the container never reconnects.
its always the same first three numbers but the last one changes and im trying to figure out why.
For example mouse search reports the following:
Direct Server IP: 212.102.39.105
Mousehole IP: 212.102.39.87
and on start gluetun reports:
Public IP address is 212.102.39.17

Both mousehole and mousesearch are behind the vpn using the network_mode: container:gluetun thing so im really not sure why they are giving different ip address.
I should also probably mention im using the PIA provider
if anyone has a clue as to why this is happening or how to fix it id be all ears.

This looks to be unrelated to Gluetun and something that PIA is doing:
