ProxyARP Subnetting HOWTO

This HOWTO discusses using Proxy Address Resolution Protocol (ARP) with subnetting in order to make a small network of machines visible on another Internet Protocol (IP) subnet (I call it sub-subnetting). This makes all the machines on the local network (network 0 from now on) appear as if they are connected to the main network (network 1).

This is only relevent if all machines are connected by Ethernet or ether devices (ie. it won't work for SLIP/PPP/CSLIP etc.)
