IPAddress

这个是基于VC++的，飞鸽传书源码。支持SOCKET通讯，能在局域网内进行文件传输，文字通讯。(This is based on the VC++ of IP Messenger source. Support SOCKET communications, can transfer files in the LAN, text messaging.)

这是一个关于MODEM的网络编程源代码，采用VC++编写。(This is a MODEM network programming source code, written using VC++.)

Visual C++案例开发集锦第六章\聊天室服务器端开发的程序源码,值得一看！(Visual C++ case development highlights Chapter Chat server-side development of the program source code, worth a visit!)

封装帧和解析帧，并有CRC校验，完全是自己手写(Feng binding and parsing frame, and a CRC checksum)

检测NAT类型的客户端，程序中指定了服务器IP地址，用户可以自行修改(Detect NAT type of the client, the program specifies the server IP address, the user can modify)

程序记录并显示了数据报从源端机器传送到目标机器的过程中所经过的路由器的IP地址，并且记录了数据报到达每个路由器所需要的时间。认真观察到达每个路由器的时间有什么区别，从而熟练掌握traceroute的工作原理和ICMP报文协议。　(The program records and displays the IP addresses of routers through which the datagram sent from the source client machine to the target machine , and the recording of the data packets arrive at the time required by each router . )

一个基于MFC的网络通信SOCKET程序，实现了接收SOCKET数据的同时，发送SOCKET数据。(An MFC-based network communication SOCKET procedure to achieve the same time to receive SOCKET data, send SOCKET data.)
