How to follow IP changes in LAN to avoid remote connectivity issues

I’ve set up remote access to a computer and had to enter the authorized IPs which can connect remotely to the computer. These IPs change from time to time and I have no control over that, so every time they change I have to go update the authorized IPs list. Usually, a user will let me know that the connection failed.

Is there a way to somehow track this IP changes (happening on a company’s LAN) so I can proactively update my list instead of having to wait until the connection fails to go and see what the new IP is ?

If it’s not possible, how is this usually handled by IT security professionals ?
