Many websites now use cdn technology. It is difficult to obtain the real IP address of their servers during some tests. I don't know what other good methods are available now, the following two types are available: 1: Use the CDN server to find the real IP address cache_peer 1.1.1.1 parent 80 0 no-query originserver ca

Because my website needs to query source IP to check its location information. So, I used the IP query based on the location of some things, and now the accumulation of a little something in the shared out.The first thing to say is that a similar blog has been written a few years ago (just not comprehensive enough), see: Python Gets the local IP and location Acco

This was to illustrate the communication between and the separate machines which don ' t have a direct physical connection.Application data is generated and passed to Layer 3 (network layer) which wrapps up the data with the destination IP Addre Ss. Then hands to Layer 2 (link layer) which have a lookup table of IP addresses and their corresponding MAC addresses

is used. The so-called mobile IP address refers to the technology where the same IP address can be used in multiple regions on the IP network. This technology is achieved by using a special router called Home Agent and Foreign Ag

. Simply put, a single IP Address can provide external services as a server, allowing two 48-power connections at the same time (each client uses all ports for connection) The actual number of TCP connections is the theoretical maximum number of connections on a single machine. In the actual environment, it is limited by machine resources, operating systems, and so on, especially on the sever side, the maxi

Can the IP address and computer name of the DC be changed arbitrarily? The answer is certainly not. Here's how to change the IP and computer name of a DC.One. Change the domain controller IP address. (Don't forget to change the DNS server in DHCP after you've finished changi

I recently wrote a small program to determine whether it is a domestic IP address. The Chinese version will automatically jump to the Chinese version, and the foreign version will automatically jump to the English version. It is not ideal to search many materials. In addition, many IP
