Explanation

DHCP (Dynamic Host Configuration Protocol) is the service designed specifically to automatically assign, manage, and reclaim IP addresses on TCP/IP networks - it handles the full address lifecycle, including leasing addresses for a set duration and reclaiming them when devices disconnect.

The distractors each serve entirely different purposes:

• DNS (Domain Name System) translates human-readable domain names (like google.com) into IP addresses - it looks up addresses, it doesn't assign them.
• LDAP (Lightweight Directory Access Protocol) is a directory service used for authentication and storing information about users and resources, not IP management.
• SMTP (Simple Mail Transfer Protocol) is the protocol for sending email between servers.

Memory tip: Think of DHCP as the "network landlord" - it hands out IP address leases, collects them back when the lease expires, and keeps track of who has what. The word Dynamic in its name is a direct hint that it dynamically assigns addresses rather than requiring manual (static) configuration.
