Source code distribution includes a high performance STUN server, a client application, and a set of code libraries for implementing a STUN client within an application. It is always placed in the Binding Response, and it indicates the source IP address and port the server saw in the Binding Request sent from the client, i. 一个使用STUN协议且基于JS的可用的NAT类型检查工具. In the presence of NATs, this address is allocated by the NAT closest to the STUN server. In this article we are going to consider Google STUN server and complete list of free and public stun Tagged with webdev, javascript, webrtc, programming.
