Fixed IP Addresses for Audio Devices

I'm not sure where this topic belongs... Please re-classify as necessary.
You may recall I started using fixed IP Addresses for all of my Google speakers (Chromecast, Home Hub & Home Minis) as a way to stabilize their discovery by DAS. I did that in Feb 2020, and you provided this format for the key:
Doing that greatly stabilized the casting audio performance. This week, I was adding a new Google Mini, and I learned that Comcast has eliminated the ability to assign Fixed IP Addresses**, so I was wondering if DAS has a way to use MAC Addresses instead of IP -- since MAC Addresses don't change it would provide another way to uniquely identify a speaker...
Alternatively, I am thinking of ditching Xfinity's Gateway, and using my own Router, but I first need to research if that will cause any degradation of my TV and Voice services.
**Odd that Comcast has prevented me from assigning new fixed IPs, but it has retained those that I previously assigned!!!
The MAC address is used by DAS to check if a newly discovered device is already in the device list.
You can't use the MAC address instead of IP, the IP is always used to connect to a device.
OK.... I now have to decide whether to include DHCP devices in the "key" or not...
FYI, this is the key I am referring to:
add key="IpAddressesDevices" value="192.168.1.13,Family Room Speakers;192.168.1.25,PlayRoom Speakers;192.168.1.11,Office Speakers;192.168.1.17,.............. etc."
If I do not add new devices to the above key, I am assuming they will be found through the normal means, correct?
What happens if I add a device to the key, and it's IP address later changes? Will that cause problems?
Thanks!
That's correct, they will be found through the normal means.
An IP change should be detected, the MAC address is used for that.
