IP Aliasing

[Jim B]

Is there a way to remove an alias manually (i.e. without rebooting)?

For instance, I have eth0, eth0:0, and eth0:1.

I can "down" them but they are actually still there (ifconfig -a).  How can
I remove the two aliases?

I also can't unload my ip_alias module until I get rid of those aliases.  Is
there a way to do it (without rebooting)?  I don't see a "del" for ifconfig
except the one that applies to IPv6.
