IANA is a standards organization in the world that is responsible for assigning various addressing standards. They are usually assigned dynamically to client applications when initiating a connection. It is not very common for a client to connect to a service using a Dynamic or Private Port, sometimes some peer-to-peer file sharing programs do.

Below, we take a look at these protocols, provides a basic description of their function, and lists the port numbers that they are commonly associated with. FTP is one of the most commonly used file transfer protocols on the Internet and within private networks. An FTP server can easily be set up with little networking knowledge and provides the ability to easily relocate files from one system to another. SSH is the primary method used to manage network devices securely at the command level. It is typically used as a secure alternative to Telnet which does not support secure connections. Telnet is the primary method used to manage network devices at the command level. Unlike SSH which provides a secure connection, Telnet does not, it simply provides a basic unsecured connection.

For example, port 80 is used by web servers. Port to 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. Port to These are port numbers used by client programs, such as a web browser. When you visit a web site, your web browser will assign that session a port number from within this range. As an application developer, you are free to use any of these ports. Your IP Address.

Both of these protocols are involved in the process of transmission of data. While UDP is used in situations where the volume of data is large and security of data is not of much significance, TCP is used in those situations where security of data is one of the main issues. While the transfer of data, the existence of ports is a matter of high significance. Each data packet comes with a port number associated with it. This enables the protocols to decide that what are the requirements of the data packets and to which port are they supposed to be directed.

This appendix provides a quick reference for IP addresses, protocols, and applications. This appendix includes the following sections:. This section describes how to use IPv4 addresses in the security appliance.
