Abstract

   IP addresses currently used by organizations are likely to undergo
   changes in the near to moderate term.  Change can become necessary
   for a variety of reasons, including enterprise reorganization,
   physical moves of equipment, new strategic relationships, changes in
   Internet Service Providers (ISP), new applications, and the needs of
   global Internet connectivity.  Good IP address management may in
   general simplify continuing system administration; a good renumbering
   plan is also a good numbering plan.    Most actions taken to ease
   future renumbering will ease routine network administration.

   Routers are the components that interconnect parts of the IP address
   space identified by unique prefixes.  Obviously, they will be
   impacted by renumbering.  Other interconnection devices, such as
   bridges, layer 2 switches (i.e., specialized bridges), and ATM
   switches may be affected by renumbering.  The interactions of these
   lower-layer interconnection devices with routers must be considered
   as part of a renumbering effort.

   Routers interact with numerous network infrastructure servers,
   including DNS and SNMP.  These interactions, not just the pure
   addressing and routing structure, must be considered as part of
   router renumbering.
