So why don't you get a laptop and try it out? Using a virtual machine
will not tell you what the behavior is if the network address is
forcibly changed on the machine, and there are other confounding
circumstances here like loss of network carrier when you change
location etc. (It may be possible to conduct a principled experiment
with virtual machines but it will not be particularly easy.)

You will have to make sure that the daemon continues to permit remote
logins on every new address it acquires.

Many things are unpleasant to maintain but provide necessary
functionality. Again, what you should do is conduct an actual test.
