If you do get pushed to doing that, there are a few commonly used
networks that you should avoid. 10. is often used with a netmask of
/24 or /8, and the latter precludes all 10. variants. Of the 192.168.
groups, 0, 1, 8, 16 and 254 are often used, best use something quite
random like 192.168.137.0/24.

Probably better still is one of the 172.16-172.31 groups, which don't
seem to be used as defaults very often.
