1.  Introduction

   This document specifies the syntax and semantics of the Uniform
   Resource Identifier (URI) scheme for the Session Traversal Utilities
   for NAT (STUN) protocol.

   STUN is a protocol that serves as a tool for other protocols in
   dealing with Network Address Translator (NAT) traversal.  It can be
   used by an endpoint to determine the IP address and port allocated to
   it by a NAT, to perform connectivity checks between two endpoints,
   and used as a keepalive protocol to maintain NAT bindings.  RFC 5389
   [RFC5389] defines the specifics of the STUN protocol.

   The "stun" and "stuns" URI schemes are used to designate a standalone
   STUN server or any Internet host performing the operations of a STUN
   server in the context of STUN usages (Section 14 RFC 5389 [RFC5389]).
