What is a dynamic IP address?

A dynamic IP address is assigned to a device that may change over time. This type of IP address is typically assigned by a DHCP (Dynamic Host Configuration Protocol) server, which automatically allocates IP addresses from a pool to devices on a network. Because the address can be reused by different devices at different times, it allows for more efficient use of available IP addresses, especially in environments where devices frequently join and leave the network.

Dynamic IP addresses are particularly beneficial for home and smaller networks, as they simplify the management of IP address allocation. Unlike static IP addresses, which remain constant, dynamic addresses can be associated with various devices, allowing for flexibility and scalability. This characteristic helps minimize unassigned or idle addresses, ensuring that the limited number of IPs are utilized effectively.
