I used route -n to show the full numeric output. Vis the diference
between route and route -n...

route

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface 203.59.0.253    *               255.255.255.255 UH    0      0    
   0 ppp0 localnet        *               255.255.255.0   U     0      0
       0 eth0 default         203.59.0.253    0.0.0.0         UG    0   
  0        0 ppp0

route -n

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface 203.59.0.253    0.0.0.0         255.255.255.255 UH    0      0    
   0 ppp0 192.168.0.0     0.0.0.0         255.255.255.0   U     0      0
       0 eth0 0.0.0.0         203.59.0.253    0.0.0.0         UG    0   
  0        0 ppp0

The *'s are realy 0.0.0.0's 
 
So... anybody seen any serious goofs yet?
