You obviously don't have to specify these netmasks though.  For a dedicated
VPN, using a 192.168.$[RANDOM%256].$[RANDOM%256] network with a /30 netmask
would probably never conflict with a local network and would provide the
two IPs necessary for communications.

I use my own DNS cache and tell dhclient to always use that one.  In a few
rare cases that will break when they are doing DNS-based captive portals,
but those are pretty rare these days.
