How are IP addresses often assigned in a network?

IP addresses are commonly assigned through DHCP (Dynamic Host Configuration Protocol) services, which automate the process of IP assignment within a network. DHCP allows devices to join a network and receive an IP address along with other network configuration details such as subnet mask, default gateway, and DNS servers without manual intervention. This dynamic assignment is efficient and helps manage the IP addresses centrally, minimizing potential conflicts and simplifying network administration.

While manual input from administrators is a viable method for setting static IP addresses, it does not reflect the common approach in most networks, especially those with a large number of devices. The use of network cables pertains to the physical connectivity of devices rather than IP assignment. End users at their devices might have some control over specific settings, but they typically do not manage the overarching IP assignment process, especially in a managed network environment where DHCP is employed.
