What are static IP and dynamic IP? What is the difference between them? Which one is better? Regarding this question, it is not difficult to find that there are many explanations on Zhihu and Zhihu, but according to the editor's discovery, these answers are all professional terminology explanations about static IP and dynamic IP, which ordinary non-professional personnel cannot understand at all. So, today the editor will explain it to you based on many years of experience in the IP industry:
What is a static IP: A static IP is also called a long-term IP. It is an external IP address that remains unchanged for a long time or forever. It is suitable for users with long-term stable IP. Where can we see it? The server IP used to build a website is a fixed static IP address. In addition to building a website, the server can also be used to build a proxy IP.
Advantages of static IP: 1. Better stability. The hardware and software resources of a server belong to you alone, which is more secure in use. 2. Higher security. One IP address is only used by you. 3. Fewer management and after-sales problems. Static IPs belong to independent servers. There will be fewer after-sales problems and it is also very convenient to handle.
Disadvantages of static IP: 1. Since the IP is a fixed IP assigned by the operator, it is too simple and limited for non-business special requirements, and the price is relatively high.
What is a dynamic IP: A dynamic IP is also called a short-term IP. An IP address will become invalid and change to a new IP address within a certain period of time. There are currently two forms of dynamic IP in the market: 1. When the optical modem of a home broadband is restarted, the IP will change (in daily use, generally not noticeable). 2. A short-term HTTP proxy built through a dial-up VPS server uses a fixed server IP. After a certain period of time, the IP expires and a new IP is obtained for use.
Advantages of dynamic IP: 1. Rich IP resources, covering all provinces and cities across the country, with high availability. 2. More commercial uses (big data collection business), adaptable to a wide range of businesses. 3. Low price, high price-performance ratio, easy to operate, and highly convenient.
Disadvantages of dynamic IP: 1. The IP pool is shared (there are only these IPs in China), and the usage rate is determined by your own business. 2. Bandwidth resources are limited, and the use is slower than static IP. The above is a non-professional terminology introduction to static IP and dynamic IP, as well as the advantages and disadvantages of the two. So, which one is better, static IP or dynamic IP?
A: It depends on your needs.
