I've never seen that one, most default networks I've seen have been
192.168.0., 192.168.1. or 192.168.254. Occasionally 192.168.16.

But it should be a matter of course to change a new router's network to
something fairly random, when you change the admin password. No, you (or
your mother) don't want to use a VPN now, but one day you might.
