Dynamic IP and static IP are two concepts often used in proxy networks. Static IP addresses are directly assigned by ISP service providers, and the linked network remains static. Dynamic IP is provided by ISP service providers and then assigned to the user's device via DHCP, continuously generating dynamic IP addresses for their computers within the organization's network.
Dynamic IP
A dynamic IP address is one that is dynamically assigned to a computer by an ISP. Every time you restart your computer (or router), the ISP will use the DHCP protocol to dynamically assign an IP address to a network device. Because the ISP dynamically assigns IP addresses to computing devices when they are restarted, your device may not receive the same IP address that was previously assigned to it.
Since IP address resources are very precious, most users use dynamic IP addresses to access the Internet. For example, computers that access the Internet through modem, ISDN, ADSL, cable broadband, community broadband, etc., are temporarily assigned an IP address each time they access the Internet.
Static IP
A static IP address is an IP address that is permanently assigned to a computer or network device. When the operator assigns a fixed IP, it will also inform the user of the corresponding mask and gateway. The user can then configure this IP in the local connection, and there is no need to re-acquire the IP when the device is turned on. Generally, only special servers or computers that use dedicated lines to access the Internet have fixed IP addresses, and they require relatively expensive fees.
The difference between dynamic IP and static IP
1. The biggest difference between dynamic IP and static IP is whether the IP changes after being assigned to a device. Whether it is a public network IP or an intranet IP, there is a difference between dynamic and static. For example, when you turn on your computer and enter the network settings, if you see "automatically obtain an IP", then the IP of this device will change randomly. If the network sees a specified IP, then it is a static IP address.
2. Static IP is generally used for commercial purposes (such as server rooms), while ordinary users use dynamic IP addresses to access the Internet.
3. The Internet speed provided by the ISP to each user is not limited by the IP address, but by the physical line connecting the user to the ISP, so static or dynamic does not have much impact on the Internet speed.
