you don't have to list the broadcast or netmask, if they can be guessed |
| 9 |
from context. In the case of using a 192.168.x/24 network they can |
| 10 |
generally both be guessed properly, because that's a Class C private |
| 11 |
address . |
| 12 |
|
| 13 |
However, in the case of 10.0.0/24, this may not be true. that is |
| 14 |
defined as class A private address space, and the networking utilities |
| 15 |
would probably assume it was 10.0.0/8, a netmask of 255.0.0.0 and a |
| 16 |
broadcast of 10.255.255.255. That is what ifconfig does at least: |
| 17 |
|
| 18 |
pascal ~ # ifconfig eth0:1 10.0.0.1 |
| 19 |
pascal ~ # ifconfig eth0:1 |
| 20 |
eth0:1 Link encap:Ethernet HWaddr 00:50:70:56:2E:CA |
| 21 |
inet addr:10.0.0.1 Bcast:10.255.255.255 Mask:255.0.0.0 |
| 22 |
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 |
| 23 |
Interrupt:225 Base address:0xc000 |
| 24 |
|
| 25 |
ifconfig is probably being used to configure your interfaces, unless |
| 26 |
you switched to iproute2. |
