The idea is that you can plug machines into a local network and have
them talk to each other with no setup and no preconfigured DHCP service.
Each picks some more-or-less random and hopefully unique address in
this subnet. Windows boxes will do it if a DHCP request times out.
Machines can find and access each other by name with broadcast based
naming like netbios or dns over multicast like rendezvous.
