Public IP serves as unique identifiers for devices on a network. Data is directed accurately to the intended destination, enabling seamless communication within the network.

Public IP enables geolocation services, aiding in the tracking of the physical location of devices or users connected to the network. This is useful for various applications, such as optimising services based on user location or assisting in the recovery of lost or stolen devices.

Public IP addresses allow devices to access resources and services, both on the internet and within a local network.

IP addresses support security protocols and facilitate user authentication. By incorporating security measures at the IP level, networks can authenticate users and devices, control access to sensitive information, and protect against unauthorised activities.
