In network communication, the importance of IP addresses is well known. In actual use, static IP and dynamic IP are two common choices. However, many people tend to confuse the usage scenarios of the two, which leads to confusion and errors. This article will introduce the differences in the usage scenarios of static IP and dynamic IP to help readers better understand.
I. Definition
First, let's understand the definition of static IP and dynamic IP. Static IP means that in network communication, the IP address assigned to the network device is fixed; while dynamic IP means that the IP address is dynamically assigned by the network service provider and may change every time you reconnect.
2. Applicable Scenarios
Static IP is suitable for scenarios that require long-term stable connection. For example: brand protection, email guarantee, media matrix and other businesses that require long-term operation and stable connection, because static IP address is fixed and can ensure the stability and reliability of business connection;
Dynamic IP is suitable for scenarios that require frequent and large-scale use of IP, such as data collection. Since dynamic IP is dynamically allocated by the network service provider, users may obtain different IP addresses each time they reconnect. In this way, it can better cooperate with the development of data services.
3. Characteristics
In addition, static IP and dynamic IP are also different in the way of obtaining: if you want to obtain a static IP, you generally need to apply to the ISP, or purchase it from a proxy service provider, and perform additional configuration and management; while dynamic IP is generally provided free of charge and is achieved through automatic allocation. Static IP is stable enough, and dynamic IP is more flexible in some scenarios.
Of course, there are overlapping usage scenarios for the two. When the access speed requirement is high but the privacy requirement is not high, both static IP and dynamic IP can meet the needs. We should flexibly choose according to actual needs.
