. as default gateway
 

When I was looking at the routing table of a CentOS 5.2 box, I noticed that the output of `route` showed the default gatewat as . (a dot). What does this mean?

I did some extensive googling, but all references to the 'route' command (CentOS-specific or not) did not show that.

what are you running to get this? Could this be a weird DNS result? add -n to the route command if it's not already there..?

I run 'route' to use this output.
'route -n' outputs as exprected.
The gateway is set to an ip address in the same subnet as eth0 in /etc/sysconfig/network.
There seem to be no problems in traffic, yet I still do not understand what it means.

so it does go away with a -n? DNS then. what does the response from "host your.gateway.ip.here" say?
