Which service provides dynamic IP addresses to clients on a LAN?

• A. DHCP Server
• B. DHCP Client
• C. IP Addressing
• D. ARP Table

Answer: (A)

Dynamic IP addresses on a LAN are provided by a DHCP server. This server runs the Dynamic Host Configuration Protocol and holds a pool of available IP addresses. When a client connects, it sends a request, and the server assigns an IP from the pool along with other settings like the subnet mask, default gateway, and DNS servers. The lease may be renewed or reissued as needed, allowing devices to join the network without manual IP configuration. The DHCP client is the device that requests an IP, not the one that hands them out. IP addressing is the overall process of assigning IPs, but it isn’t a service by itself. The ARP table is used to map IP addresses to MAC addresses after devices have IPs assigned, helping with local delivery of frames, but it doesn’t assign IP addresses.
