you don't have to list the broadcast or netmask, if they can be guessed
from context. In the case of using a 192.168.x/24 network they can
generally both be guessed properly, because that's a Class C private
address .
However, in the case of 10.0.0/24, this may not be true. that is
defined as class A private address space, and the networking utilities
would probably assume it was 10.0.0/8, a netmask of 255.0.0.0 and a
broadcast of 10.255.255.255. That is what ifconfig does at least:
pascal ~ # ifconfig eth0:1 10.0.0.1
pascal ~ # ifconfig eth0:1
eth0:1 Link encap:Ethernet HWaddr 00:50:70:56:2E:CA
inet addr:10.0.0.1 Bcast:10.255.255.255 Mask:255.0.0.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
Interrupt:225 Base address:0xc000
ifconfig is probably being used to configure your interfaces, unless
you switched to iproute2.
