To get around the floating address problem.  SUSE assigns the
hostname to ONLY a secondary local interface IP...

172.0.0.2     myhostname.domain.com myhostname

This only breaks buggy software that make too many
assumptions (unfortunately there's quite a bit of
that out there).

Routable (internal/external) address is usually retrieved
from a name server or such.
