         Internet Protocol Version 6 (IP, RFC 1883/1884), IPv6

From The Free On-line Dictionary of Computing (30 December 2018) :

  Internet Protocol version 6
      (IPv6, IPng, IP next generation) The
     most viable candidate to replace the current Internet
     Protocol.  The primary purpose of IPv6 is to solve the
     problem of the shortage of IP addresses.
     The following features have been purposed: 16-byte addresses
     instead of the current four bytes; embedded encryption - a
     32-bit Security Association ID (SAID) plus a variable length
     initialisation vector in packet headers; user
     authentication (a 32-bit SAID plus variable length
     authentication data in headers); autoconfiguration
     (currently partly handled by Dynamic Host Configuration
     Protocol); support for delay-sensitive traffic - a 24 bit
     flow ID field in headers to denote voice or video, etc.
     One possible solution is based on the TUBA protocol (RFC
     1347, 1526, 1561) which is itself based on the OSI
     Connectionless Network Protocol (CNLP).  Another is TP/IX
     (RFC 1475) which changes TCP and UDP headers to give a
     64-bit IP address, a 32-bit port number, and a 64-bit
     sequence number.
     RFC 1550 is a white paper on IPng.
