i have ideas about this but they would take time and money :). basically
this type of situation is solved by dhcp. that means you would have to
have a dhcp server at school and at home-which means a firewall or
something at each place so that your dhcp server doesnt confuse the dhcp
server they might be running at upmc and verizon. there may be better
ways, but this is what i see.

in redhat 7.1
/etc/rc.d/init.d/network  restart

should do it.
