Types Of WAN IP Modes: Static Vs. Dynamic
A WAN IP mode refers to the method by which an Internet Service Provider (ISP) assigns an IP address to a device or network. There are two main types of WAN IP modes: static and dynamic.
Static WAN IP mode involves the ISP assigning a fixed IP address to the device or network. This means that the IP address remains unchanged over time, providing a reliable and consistent connection. Static IP addresses are typically used in situations where remote access, such as VPN connections or hosting services, is required. They are also beneficial for certain types of applications that require a dedicated IP address for proper functionality.
On the other hand, dynamic WAN IP mode involves the ISP assigning a temporary IP address to the device or network. This IP address is randomly selected from a pool of addresses and is subject to change each time the device reconnects to the network. Dynamic IP addresses are more commonly used for home internet connections or small businesses with basic networking needs.
Both static and dynamic WAN IP modes have their respective benefits and drawbacks, and selecting the right mode depends on the specific requirements and limitations of the network or device.
