DHCP - Static binding use cases

A DHCP static binding is one where the DHCP server has reserved a particular IPv4 or IPv6 address to be assigned to a specific host with a specific client ID.

A static DHCP binding is useful in environments where you want a specific IP address to always be assigned to a specific host, based on its MAC address or more generally, its client ID. This is often used for servers, printers, IP cameras, network equipment, or any device that needs a consistent IP address. This approach is scalable, delivers centralized control, and easier management, however, it depends upon DHCP which may become a single point of failure.

Alternatively, one can use a manual IP assignment on the device itself, independent of any DHCP server. This is more labor intensive, less scalable, and more difficult to manage, especially for larger networks, but doesn’t critically depend upon DHCP.
