No route for localhost?

Hi!

When I type the following command:
$ route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref
Use Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 303 0
0 wlan0
0.0.0.0 192.168.1.1 0.0.0.0 UG 303 0
0 wlan0

Why I don't have an entry for localhost? Like:
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo

PS: My system works perfectly

Thanks

"route -n" shows only the "main" routing table, which contain only
routes to external unicast destinations. Routes to local and broadcast
destinations are in the "local" routing table which can be displayed
with the following command (requires the iproute package to be installed) :

$ ip route show table local

Note : The "local" routing table has precedence over all other routing
tables, including "main". So local and broadcast routes cannot be
overriden by adding routes in the "main" routing table.

Thanks!

Another question: it seems that the functionalities of 'route' are
contained in 'ip'. Is that true?

Yes. "ip" can do what "route" does, and much more. You shouldn't be using
"route" (and "ifconfig", for that matter) anymore these days.
