In order to communicate among themselves, ad hoc nodes (refer to RFC
  2501) need to configure their network interface(s) with local addresses
  that are valid within an ad hoc network. Ad hoc nodes may also need to
  configure globally routable addresses, in order to communicate with
  devices on the Internet. From the IP layer perspective, an ad hoc
  network presents itself as a L3 multi-hop network formed over a
  collection of links.
  
  The main purpose of the AUTOCONF WG is to describe the addressing model
  for ad hoc networks and how nodes in these networks configure their
  addresses. It is required that such models do not cause problems for ad
  hoc-unaware parts of the system, such as standard applications running
  on an ad hoc node or regular Internet nodes attached to the ad hoc
  nodes. This group's effort may include the development of new protocol
  mechanisms, should the existing IP autoconfiguration mechanisms be found
  inadequate. However, the first task of the working group is to describe
  one practical addressing model for ad hoc networks.
  
  Once this sole work item is completed, the group can be rechartered to
  work on additional issues.
