INTRODUCTION

   This	Network	Working	Group Request for Comments documents the
   currently assigned values from several series of numbers used in
   network protocol implementations.  This RFC will be updated
   periodically, and in	any case current information can be obtained from
   the Internet	Assigned Numbers Authority (IANA).  If you are developing
   a protocol or application that will require the use of a link, socket,
   port, protocol, etc., please	contact	the IANA to receive a number
   assignment.
