But then I seem to have seen an example in one of the OReill=A5 books on networking that had one interface with one assigned inet address and also aliased with another address that could only be on another network. If I understood that right, it seems to imply that I can use one Network interface card for at least two different networks, like so; 192.168.1. and alias 172.0.0. or; 192.168.1. alias 192.168.2. If this is possible is it accomplished via a special routing? My concern is that I have a laptop with one network interface, built in, but would like to access it both at a public static address and a private network address. Is this possible? Thanks in advance for time and attention; Jeff K
