The RFC is actually real, though it it basically a joke: www.rfc-editor.org/rfc/rfc2322

Management of IP numbers by peg-dhcp

Introduction This RFC describes a protocol to dynamically hand out ip-numbers on field networks and small events that don’t necessarily have a clear organisational body.

History of the protocol.

The practice of using pegs for assigning IP-numbers was first used at the HIP event (www.hip97.nl). HIP stands for Hacking In Progress, a large three-day event where more then a thousand hackers from all over the world gathered. This event needed to have a TCP/IP lan with an Internet connection. Visitors and participants of the HIP could bring along computers and hook them up to the HIP network.

During preparations for the HIP event we ran into the problem of how to assign IP-numbers on such a large scale as was predicted for the event without running into troubles like assigning duplicate numbers or skipping numbers. Due to the variety of expected computers with associated IP stacks a software solution like a Unix DHCP server would probably not function for all cases and create unexpected technical problems.
