registered port numbers: The registered port numbers are the port number s that companies and other users register with the Internet Corporation for Assigned Names and Numbers ( ICANN ) for use by the applications that communicate using the Internet's Transmission Control Protocol ( TCP ) or the User Datagram Protocol ( UDP ). In most cases,
These ports are assigned to specific server sevice by the Internet Assigned Numbers Authority (IANA). For example, port 80 is used by web servers. Port 1024 to 49151: These are ports that an organization, such as application developers, can register with IAMA to be used for a particular service. These should be treated as semi-reserved.

There are clearly defined port numbers for every popular or well-known TCP/IP application. A port number is a 16-bit value between 0 and 65,535. Within this range of ports, some port numbers are established for specific services, some are reserved for certain applications, and others are available for temporary use by applications.
A port is an extension of an address, similar to adding an apartment or room number to a street address. A letter with a street address will arrive at the correct apartment building, but without the apartment number, it will not be delivered to the correct recipient. Ports work in much the same way. A …

There are different types of port numbers: Well Known Ports (Numbers 0 to 1023) - These numbers are reserved for services and applications. They are commonly used for applications such Well-known port numbers are port numbers for Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) that have been assigned to specific TCP/IP applications or services by the Internet Assigned Numbers Authority (IANA).

Nov 05, 2019 · A process called network port scanning detects test messages at each port number to identify which ports are open. Network professionals use port scanning as a tool to measure exposure to attackers and often lock down networks by closing non-essential ports. Hackers, in turn, use port scanners to probe networks for open ports that may be The well known ports are assigned by IANA in the range of 0 to 1023. The port numbers will be shown after the IP address and the two are separated by a colon. For instance, if your IP address is something like 192. 168. 45. 2 and you’re being displayed an entry for 192. 168. 45. 2: 57961, it means the port number 57961 is open. What does a port scanner do?
