Dynamic IP addresses are random IP addresses that are assigned when needed. Dynamic IP address and static IP address are corresponding, the so-called dynamic means that every time you go online, Telecom will randomly assign an IP address, static refers to the fixed allocation of an IP address, every time you use this address. Because IP address resources are very valuable, the IP addresses used by most users when surfing the Internet are dynamic, just like computers that access the Internet through modem, isdn, adsl, wired broadband, cell broadband, etc., are temporarily randomly assigned an IP address every time they go online.

An IP address is a 32-bit binary number of addresses, and theoretically, there are about 4 billion (2 to the 32nd power) possible address combinations, which seems like a large address space. Actually, according to....

It is a dynamic IP, to the intranet.

It is also a dynamic IP, and the mobile phone is also a dynamic IP at this time; If the external network is a static IP address, and if the intranet is a dynamic IP, the mobile phone is still a dynamic IP. Relative to the external network is a dynamic IP, but the intranet is a dynamic IP, then the mobile phone is a dynamic IP (that is, not fixed); If the external network is a static IP, but the internal network is still a static IP, the mobile phone is a static IP (fixed IP).

Note: IP protocol.

Another very important element is that every computer and other device on the Internet is assigned a unique address, called an "IP address."

Because of this unique address, it is possible for users to efficiently and easily select the objects they need from thousands of Kjeldahl computers when operating on a computer connected to the Internet.
