Here is an example:
piper:~# ip a flush dev eth0
#[318]
piper:~# ip a s dev eth0
#[319]
5: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 4e:80:ba:7e:34:14 brd ff:ff:ff:ff:ff:ff
piper:~# ip a a 10.0.0.1/16 dev eth0
#[320]
piper:~# ip a a 10.0.0.1/32 dev eth0
piper:~# ip a a 172.16.0.100/12 dev eth0
#[321]
piper:~# ip a a 172.16.0.200/12 dev eth0
#[322]
piper:~# ip a a 192.168.128.127/24 dev eth0
#[323]
piper:~# ip a a 192.168.128.129/25 dev eth0
#[324]
piper:~# ip a s dev eth0
#[327]
5: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 4e:80:ba:7e:34:14 brd ff:ff:ff:ff:ff:ff

inet 192.168.128.129/25 scope global eth0Note how only 172.16.0.200/12 is a secondary address. I can remove every address individually, but if I remove 172.16.0.100/12, then 172.16.0.200/12 is also deleted. This seems to be because they are both in the same network, 172.16.0.0/12. I don't understand the rationale. Either this is a feature, then the manpage should explain the motivation. Or it's a bug, then it should be fixed. I hope it's the latter. -- .''`. martin f. krafft <[EMAIL PROTECTED]> : :' : proud Debian developer, author, administrator, and user `. `'` http://people.debian.org/~madduck - http://debiansystem.info `- Debian - when you have better things to do than fixing systems
