DON'T USE IFCONFIG AND fooN:M ALIASES IF YOU CAN HELP IT.  Use the
iproute2 utility 'ip' and assign multiple addresses with

# ip address add <address> dev <device>

And you can add as many addresses as the kernel will let you (what's the
limit?).  Make sure aliasing support is on in the kernel.

Honestly I'd avoid using route and ifconfig at all.  Replace them
everywhere you can with 'ip'.

This doesn't answer your question, but I considered it a Public Service
Message. :)
