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 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 stand- alone STUN server or any Internet host performing the operations of a STUN server in the context of STUN usages (Section 14 of RFC 5389 [RFC5389]). With the advent of standards such as WebRTC [WEBRTC], we anticipate a plethora of endpoints and web applications to be able to identify and communicate with such a STUN server to carry out the STUN protocol. This implies that endpoints and/or applications must be provisioned with the appropriate configuration to identify the STUN server. Having an inconsistent syntax adds ambiguity and can result in non-interoperable solutions and implementation limitations. The "stun" and "stuns" URI schemes help alleviate most of these issues by providing a consistent way to describe, configure, and exchange the information identifying a STUN server. 2.
