1.  Introduction and Motivation

   The concepts of an RPC (defined in RFC 5531 [4]) Network Identifier
   (netid) and an RPC Universal Address (uaddr) were introduced in RFC
   1833 [1] for distinguishing network addresses of multiple protocols
   and representing those addresses in a canonical form.  RFC 1833
   states that a netid "is defined by a system administrator based on
   local conventions, and cannot be depended on to have the same value
   on every system".  (The netid is contained in the field r_netid of
   the data type rpcb_entry, and the uaddr is contained in the field
   r_addr of the same data type, where rpcb_entry is defined in RFC
   1833.)  Since the publication of RFC 1833, it has been found that
   protocols like Network File System version 4 (NFSv4.0) [5] and RPC/
