fixed address listing on machines with no addresses

currently the shell script used to list 10.0.0.0/8 range of addresses on
a machine would fail with exit code 1 if no addresses were present in
that range (i.e. grep did not match anything). this fix just makes sure
that command always returns exit code 0.
