Technical Summary Session Traversal Utilities for NAT (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. It can also be used to check connectivity between two endpoints, and as a keep-alive protocol to maintain NAT bindings. STUN works with many existing NATs, and does not require any special behavior from them. STUN is not a NAT traversal solution by itself. Rather, it is a tool to be used in the context of a NAT traversal solution. In keeping with its tool nature, this specification defines an extensible packet format, defines operation over several transport protocols, and provides for two forms of authentication. This document obsoletes the original STUN specification RFC 5389. Working Group Summary The working group had a strong consensus around this draft. Document Quality Marc Petit-Huguenin reported that he has implemented this draft. The document quality is satisfactory. The draft has sections pertaining to security and DNS, and those are sufficiently reviewed. Personnel Tolga Asveren is the document shepherd. Spencer Dawkins is the responsible Area director.
