What Is a Dynamic IP Address?

A dynamic IP address is an internet address that is automatically assigned to a device by a network and can change over time.

Internet service providers use a system called DHCP (Dynamic Host Configuration Protocol) to assign and manage these addresses.

This allows networks to efficiently distribute IP addresses to many users.
