Every machine that connects to the internet or a local network needs an IP address—a unique identifier that allows it to communicate with other devices. But how do these machines get their IP addresses?
Dynamic IP Addressing (via DHCP)
The most common way is through Dynamic Host Configuration Protocol (DHCP). When a machine joins a network, it sends a request for an IP. A DHCP server responds by assigning a temporary IP address automatically. This is fast, efficient, and used in most home and office networks.
Static IP Addressing
In some cases, a device may be assigned a static IP address—a fixed address that doesn’t change. This is often used for servers, printers, or devices that need to be easily located on a network.
Auto-Configuration (APIPA)
If a device fails to find a DHCP server, it may use Automatic Private IP Addressing (APIPA) to assign itself an IP in a limited range (169.254.x.x), which only works for small local networks.
Manual Entry
Advanced users or administrators can also assign an IP address manually through the system settings.
✅ In summary: Machines can get IP addresses dynamically through DHCP, statically through manual setup, or by auto-configuration if no server is found.
