What size of a network to route through the link - by default. You use
the netmask on a P2P link to determin what netmask to install in the
routeing table.

ie.
	ifconfig ppp0 1.1.1.1 2.2.2.2 netmask 255.255.255.0

*should* install a route of 2.2.2.0/24 (I believe). Whether this
is true in practise is someone elses problem... and whether it only
installs the route when the interface is UP is another question too.
