What range do registered ports fall under?

• A. 1,024-49,151
• B. 0-1,023
• C. 49,152-65,535
• D. 0-65,535

Answer: (A)

Registered ports fall within the range of 1,024 to 49,151. These ports are assigned by the Internet Assigned Numbers Authority (IANA) for specific services or applications that are not widely recognized. This allows applications that are not widely used to have a designated port for their use, while still preventing conflicts with well-known ports, which fall under the range of 0 to 1,023. The higher range of ports, from 49,152 to 65,535, is reserved for dynamic or private ports that can be used by applications as needed without requiring registration. The entire range of 0 to 65,535 encompasses all possible port numbers but does not specifically indicate the designated purposes of the registered ports. Therefore, the correct range of registered ports is accurately identified as 1,024 to 49,151.
