How to understand dynamic ip, in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Computers that surf the Internet through Modem, ISDN, ADSL, cable broadband, residential broadband, etc., each time the IP address assigned to the Internet is different, this is the dynamic IP address. Because IP address resources are very valuable, most users surf the Internet through dynamic IP addresses. The so-called dynamic means that every time you surf the Internet, Telecom will randomly assign you an IP address. Static means to use an address every time you surf the Internet. Browsers that can display your IP address are generally incorrect, for example: surfing the Internet at home. Both ADSL and dialing are dynamic and are randomly assigned to you by telecom. And it's timing. If you restart ADSL, it will change. An IP address is a 32-bit binary address, which in theory has about 4 billion possible address combinations (2 to the 32), which seems to be a large address space. In fact, according to the different bit rules of network ID and host ID, IP addresses can be divided into A (7-bit network ID and 24-bit host ID), B (14-bit network ID and 16-bit host ID), C (21-bit network ID and 8-bit host ID). Due to historical reasons and technological development, class An addresses and class B addresses are almost completely allocated, and only class C addresses can be assigned by countries and organizations all over the world. So IP address is a very important network resource.

The concept of dynamic ip

For an organization that has set up an Internet service, because its host computer opens access services such as WWW, FTP, E-mail and so on, it usually publishes a fixed IP address to facilitate users to access it. Of course, digital IP is not easy to remember and recognize, and people are more accustomed to accessing hosts through domain names, but domain names still need to be translated into IP addresses by domain name servers (DNS). For example, your home address can be easily memorized and used by users, and the domain name server will translate the domain name into 101.12.123.234, which is your real address on the Internet.

For most dial-up users, it is not advisable to assign a fixed IP address (static IP) to each user because of the discreteness of their time and space, which will result in a great waste of IP address resources. Therefore, these users usually get a dynamic IP address automatically after dialing the host of ISP. Of course, the address is not arbitrary, but an address in the legal range of the network ID and host ID applied for by the ISP. The IP address of a dial-up user is likely to be different for any two connections, but the IP address remains the same for each connection time.

Because of the characteristic of dynamic ip, the cost and price of dynamic ip is very expensive. Llidc,com of Guangdong Lilian Technology Co., Ltd. (referred to as "Lilian Technology") is a leading IDC integrated service provider in China, specializing in providing IDC value-added services such as Internet security protection, server rental hosting, large bandwidth of cabinets, etc., headquartered in Dongguan. It has obtained the value-added telecom service operation license (ICP/ISP) issued by the Ministry of Industry and Information Technology.
