If IT insists on changing IP and Hostname, you are pretty much stuck. Autodiscovery, as suggested by Lincoln and others is a good alternative to using IP Addressses in IP table. But, that¡¯s no help if hostnames change. Having IT create DNS entries for devices would work, but if they have some odd security requirement to scramble device addresses, they would probably want to change the FQDN as well.
If your IT department is reasonable/cooperative, maybe they can explain the real motivation for making these changes every 2 months. Perhaps there are other options to achieve security requirements without ¡°breaking¡± all your Crestron systems.?
Depending on their goals, an option (that would also provide actual security) would be to isolate the Crestron devices behind a firewall or use managed switches to create Allow lists to prevent unknown devices from reaching the Crestron processors. ¡°Zero trust¡± is the current trend in network security. In simple terms, this means nothing can access a device without permission. Changing IP/Hostnames every two months is not a security solution.?
