Thank you very much, but please forgive my ignorance...and allow me to
explain the entire situation.

The server I'm adding IPs to is in one /24, the ips I'm adding are in
another /24 (which is why I specified the netmask in the /sbin/ifconfig
statement, or it'd have auto-chosen 255.255.0.0)
I'm not sure where/when/how to execute what you've suggested.  Again,
forgive my ignorance, but if you'd explain, I'd be grateful.

Thanks,
~Ray
