Well, that looks like you have no DHCP assigned IP yet. No loopback, either! Weird!

I never have DHCP assigned IPs. My ISP uses DHCP to assign my router a real IP, but inside the premises I am lord almighty of the network.

You're right about loopback though. I didn't notice that before. I'll have to check into that.

I think I remember loop addresses previously being included in the output of netstat -nr, but I just checked, and it's not included in any of the 4 Linux boxes I have running right now (2 Fedora, 1 Ubuntu and 1 Arch). Yet I can ping and ssh to localhost on each.

I must not have been paying attention when it became implicit on Linux.

Windows has routing to push all local IPs to loopback, so I guess this is a step in the other direction. The IP stack can deal with loopback and hide it from routing. On Solaris and HP-UX I always see it. Well, not the most portable thing. Even ping output varies a lot. It's a shame they cannot get their act together on one set of network commands and facilities, consistent presentations! I was not amused when they overloaded the routing table with path MTU. At least HP seems to does it with less clutter than I recall on Solaris.
