What type of server automatically assigns each computer an IP address from a list of available addresses?

• A. DNS server
• B. Proxy server
• C. Dynamic Host Configuration Protocol (DHCP)
• D. FTP server

Answer: (C)

Automatic IP address assignment from a pool is provided by DHCP. The Dynamic Host Configuration Protocol manages a pool of IP addresses and leases one to each device that joins the network, along with other settings like the subnet mask, default gateway, and DNS servers. When a device connects, it uses a simple discovery/offer/request/acknowledgement sequence to obtain its configuration, and the lease can be renewed or released as needed. This automatic process prevents manual configuration errors and avoids IP conflicts by ensuring each device gets a unique address for a set period. By contrast, a DNS server translates domain names to IPs, a proxy server forwards requests on behalf of clients, and an FTP server handles file transfers.
