Any subnets you route within that address range must be explicitly routed anyway unless it is used on the LAN network and the loopback address does not need routing so I see no reason to expect it to have a default route. There is also another consideration. Having 2 addresses on the same subnet on the same machine can easily cause routing problems. The loopback address is 127.0.0.1/8. Another address on the same subnet on the same machine on a different interface can cause a problem. Ergo, why hassle with it. Leave it out of the routing table totally and forget it exists. > -- > Aleksandar Milivojevic <amilivojevic@xxxxxx> Pollard Banknote Limited > Systems Administrator 1499 Buffalo Place > Tel: (204) 474-2323 ext 276 Winnipeg, MB R3T 1L7 >
