Wickr will use Psiphon’s tech to guarantee your packets get where they need to go regardless of whether you’re at home, at a cafe with bad Wi-Fi or at a cafe with bad Wi-Fi in China. By defining these well-known ports for server applications, client applications can be programmed to request a connection to that specific port and its associated service.Encrypted collaboration app Wickr has added a feather to its cap with a partnership with Psiphon, provider of smart VPN tools. They are commonly used for applications such as HTTP (web server) POP3/SMTP (e-mail server) and Telnet. Well Known Ports (Numbers 0 to 1023) – These numbers are reserved for services and applications. In that case, the port number of 53 that is a well known port number is used by both protocols with this service. However, sending the requested information sometimes may require the reliability of TCP. For example, the low overhead of UDP with his short header enables DNS to serve many client requests very quickly. Some applications may use both TCP and UDP. Using both TCP and UDP is also normal sometime. We will introduce the list of the ports with short description of different port types. 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. This range is used for custom or temporary purposes and for automatic allocation of ephemeral ports. They are usually assigned dynamically to client applications when initiating a connection. The last porn number type Dynamic or Private Ports will not appear on our list because they are cannot be registered with IANA. There are different types of port numbers: Well Known Ports (Numbers 0 to 1023), Registered Ports (Numbers 1024 to 49151) and Dynamic or Private Ports (Numbers 49152 to 65535). IANA is a standards organization in the world that is responsible for assigning various addressing standards. Let’s see who makes it possible? The Internet Assigned Numbers Authority (IANA) assigns all port numbers except Dynamic or Private ports. This is a list of Internet socket port numbers used by application communication with TCP and UDP on the Transport Layer of the Internet Protocol Suite for the host-to-host communications.
