What is a port?

Computer ports are the central docking point for the flow of information from a program or the internet to a device or another computer in the network and vice versa. It’s the parking spot for data to be exchanged through electronic, software, or programming-related mechanisms. Port numbers are used for consistency and programming. The port number combined with an IP address form the vital information kept by every Internet Service Provider in order to fulfill requests. Ports range from 0 to 65,536 and basically rank by popularity.



Ports 0 to 1023 are well known port numbers that are designed for internet use, although they can have specialized purposes as well. They are administered by the Internet Assigned Numbers Authority (IANA). These ports are held by top-tier companies like Apple QuickTime, MSN, SQL services, and other prominent organizations.

Port checking is a method of determining which ports on a network are open and could be receiving or sending data. It is also a process for sending packets to specific ports on a host and analyzing responses to identify vulnerabilities. This checking process can’t take place without identifying a list of active hosts and mapping those hosts to their IP addresses. After a thorough network scan is complete and a host list is compiled, a proper port scan can take place. The organization of IP addresses, hosts, and ports allows the scanner to properly identify open or vulnerable server locations with the goal of diagnosing security levels.

The port checker reveal the presence of security in place such as a firewall between the server and the user’s device.

Both cyberattackers and administrators are able to use these scans to verify or check the security policies of a network and identify vulnerabilities; and in the attackers’ case, to exploit weak entry points.

The general protocols used for port checking are TCP (transmission control protocol) and UDP (user datagram protocol). They are both data transmission methods for the internet but have different mechanisms. TCP is a reliable, two-way connection-based transmission of data that relies on the destination’s status in order to complete a successful send. UDP is connectionless and unreliable. The data is sent without concern for the destination; therefore, it is not guaranteed that the data will even make it. There are several different methods of performing port scans using these
