It is no longer a new technology to bind multiple IP addresses to a network card at the same time, and this operation is also very simple, but do you notice that the bound IP addresses are static IP addresses. The local area network managed by the author is large and has a large number of clients. The DHCP server is used to dynamically allocate

I found a lot online,CodeThere are not many details about the principles. I 'd like to explain a few articles. One TechnologyArticle, The most important thing is to clarify the principle, if there is a complete operationSource codeAlso, the key is to clearly analyze the core part of the code.
