NAT会话穿越实用程序（STUN）是一种协议，用作其他协议处理网络地址转换器（NAT）穿越的工具。端点可以使用它来确定NAT分配给它的IP地址和端口。它还可以用于检查两个端点之间的连接，并作为保持活动的协议来维护NAT绑定。STUN与许多现有的NAT一起工作，并且不需要它们的任何特殊行为。STUN本身不是NAT穿越解决方案。相反，它是一个在NAT穿越解决方案上下文中使用的工具。这是本规范的上一个版本（RFC 3489）的一个重要变化，它将STUN作为一个完整的解决方案。本文档已废弃RFC 3489。[标准轨道]
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. This is an important change from the previous version of this specification (RFC 3489), which presented STUN as a complete solution. This document obsoletes RFC 3489. [STANDARDS-TRACK]
