LDAP operates on which port to store and retrieve information in a network directory?

LDAP, or Lightweight Directory Access Protocol, operates on port 389. This is the standard port used for LDAP communications which allows clients to access and manage directory services. This port is specifically designated for unencrypted LDAP traffic, enabling the retrieval and updating of directory information efficiently in network environments.

Port 110 is associated with the Post Office Protocol version 3 (POP3), which is used for retrieving emails from a mail server. Port 143 is used for the Internet Message Access Protocol (IMAP), which also deals with email but does so differently than POP3. Port 53 is utilized for the Domain Name System (DNS) to resolve domain names to IP addresses. Understanding these port assignments is crucial for network configuration and security management.
