It is easy to obtain the Client IP address through the Web. It can be parsed from the datagram (Request object) sent by the client to the web server. However, in actual application, the proxy server must be considered, router forwarding and so on.
The process of obtaining a MAC address is
structured and organized. The network address is planned in an organized manner based on the enterprise's specific needs and organizational structure. Generally, the planning process is based on the overall situation and overall focus, and then divided from big to small. In fact, this is the same as the actual physical address allocation principle. It must first be divided into provinces, cities, counties,
The tengda router obtains the WAN address. Today, I want to introduce two problems that occur when the WAN port of the tengda router obtains the Internet IP address. Let's take a look! 1. The tengda router cannot obtain the

This is an article about the Cisco router IP address, which is very old and should be useful to everyone, so we have selected it from the vast network. Hope you don't sink it down. We will give you a satisfactory response on how to use the IP address of the Cisco
?The answer is: no repeated data packets are received or sent repeatedly.Why? Right upstairs, every server maintains a route table. The route table determines where data packets should be sent.Why can't I receive repeated data packets?A: The client only sends data to the unique IP address on your server.Why not send data packets repeatedly?A: The route (PATH) for sending data packets is unique. If the serve
