It's actually hex format in ifconfig unless I'm missing something ;)=20
The discussion on -hackers linked earlier in this thread was actually a con=
versation about changing the output to dotted quad, then it moved on to pro=
viding a switch to allow users to specify dotted quad or CIDR notation. Obv=

 the output of established core commands unless there's good reason.
