What is a static IP address?

A static IP address is defined as a permanently assigned IP address. This means that the address does not change over time, and it remains fixed for the device it is assigned to. Static IP addresses are often used for servers, network devices, and services that require consistent access, such as web hosting, remote access, and game servers.

Static IPs provide ease of access and reliability because they do not need to be updated in DNS records or other application configurations over time. This stability is crucial for applications where consistent communication is necessary, such as virtual private networks (VPNs) or VoIP (Voice over Internet Protocol) services.

In contrast, the other options describe different types of IP addressing or concepts entirely. A dynamically assigned IP address refers to an address that can change, usually allocated by a DHCP (Dynamic Host Configuration Protocol) server. An IP address that changes frequently implies a dynamic allocation scenario as well. On the other hand, a type of domain name system is a different concept altogether, involving the system that translates domain names to IP addresses rather than the nature of the IP address itself.
