What defines a static IP address?

A static IP address is defined as one that remains constant until it is manually changed. This means that the address is assigned to a network device (such as a computer, printer, or server) and does not alter over time or due to power cycles. Static IP addresses are particularly useful in scenarios where consistent access to a specific device is required, such as remote access to servers, devices running network services, or when particular configurations are necessary.

In contrast, an IP address that changes frequently would be classified as dynamic, and these are typically assigned by DHCP (Dynamic Host Configuration Protocol) servers. Such assignments are meant to provide flexibility and efficient use of IP address allocations.

Dynamic assignments do not fit with the definition of static IPs, nor do temporary addresses intended for only a single session. Those are often used in different contexts, such as in mobile or wireless networks, typically relying on user sessions. Static IPs provide stability and predictability in network configurations, making them a staple in more permanent networking scenarios.
