How are ports classified by ranges in network protocols?

Ports in network protocols are classified into ranges as follows:

• Well-known ports: from 0 to 1023. Used by system or standard services (e.g., HTTP — 80, HTTPS — 443, FTP — 21).
• Registered ports: from 1024 to 49151. Usually assigned to applications and services that are not system services but have official registration.
• Dynamic or private ports: from 49152 to 65535. Used for temporary or private connections, often assigned dynamically by client applications.

This classification helps organize network service operations and avoid conflicts when assigning ports.
