[NTLUG:Discuss] Multiple Address question

[Stuart Johnston]

2.4.x has a new command for assigning multiple addresses to a single
device.  By default it does not define ethx:x type aliases but you can
add them if you want.  I don't think you can do a range of addresses all
at once, though.  The command looks like:

ip address add xxx.xxx.xxx.xxx dev ethx

See /usr/share/doc/iproute-2.4.7/ip-cref.ps for details.
