SANS ISC: port 5222

Notes:
Port numbers in computer networking represent communication endpoints. Ports are unsigned 16-bit integers (0-65535) that identify a specific process, or network service. IANA is responsible for internet protocol resources, including the registration of commonly used port numbers for well-known internet services.
Well Known Ports: 0 through 1023.
Registered Ports: 1024 through 49151.
Dynamic/Private : 49152 through 65535.

TCP ports use the Transmission Control Protocol, the most commonly used protocol on the Internet and any TCP/IP network. TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and that packets will be delivered in the same order in which they were sent. Guaranteed communication/delivery is the key difference between TCP and UDP.

UDP ports use the Datagram Protocol. Like TCP, UDP is used in combination with IP (the Internet Protocol) and facilitates the transmission of datagrams from one computer to applications on another computer, but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received the message to process any errors and verify correct delivery. UDP is often used with time-sensitive applications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data.

When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them. This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command. We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software. For more detailed and personalized help please use our forums.

A. - 2015-08-18 22:19 port 5222 is used on WhatsApp too by anonymous - 2020-01-25 01:50 And Warface by anonymous - 2020-01-31 12:28 Also aparently EVE Online as well. by javier - 2021-05-26 16:06 WhatsApp no longer uses port 5222, I have a very restrictive firewall with nftables. WhatsApp: 80, 443 TCP, 3478, 24774, 40284 UDP by anonymous - 2022-10-11 03:51 X-Sense smoke detectors also seem to communicate with the cloud server by this port. by anon - 2025-01-27 17:42 Whatsapp *does* use port 5222 on my machine. OpenSnitch kept reporting Firefox was trying to use port 5222. I checked the about:networking page in Firefox, and there I find a connecting to web.whatsapp.com on port 5222. The documentation of Whatsapp says that if port 5222 is not available, it falls back to port 433, so you can just block port 5222 anyway. by Franck - 2025-03-12 07:52 Hello, Port TCP 5222 is also used by Spacewalk proxies, on servers for Oracle Linux operating systems for push support to Spacewalk clients (as an example, for the update of an operating system of a client).
