Which server automatically assigns IP addresses from a pool of available addresses?

• A. Dynamic Host Configuration Protocol
• B. Domain Name System
• C. Proxy Server
• D. Web Server

Answer: (A)

IP addresses can be assigned automatically by a service called DHCP. A DHCP server maintains a pool of available addresses and hands one to a device when it connects, along with other network settings like the subnet mask, default gateway, and DNS servers. This process happens automatically through a lease mechanism, allowing devices to join the network without manual configuration and reducing the risk of duplicate addresses. The other functions listed don’t perform this automatic IP assignment: DNS translates hostnames to IP addresses, a proxy server acts as an intermediary for requests and caching, and a web server delivers web content.
