A static IP address is an IP address that was manually configured for a device, versus one that was assigned via a DHCP server.
A static IP address is called static because it doesn’t change. This is the exact opposite of a dynamic IP address, which does change.
Static IP addresses are also sometimes referred to as fixed IP addresses or dedicated IP addresses.
