Registered ports are network port numbers that fall within the range of 1024 to 49151. These ports are not as widely recognized as well-known ports (0-1023), but they are reserved by the Internet Assigned Numbers Authority (IANA) for specific applications and services. Registered ports are used for a variety of purposes and are typically associated with less common or proprietary services. Here are some examples of registered ports and the services or applications they are associated with:
- Port 1080: Used for SOCKS proxy, a protocol for routing network packets between a client and a server through a proxy server.
- Port 1433: Associated with Microsoft SQL Server, a relational database management system.
- Port 1521: Used by Oracle Database for network communication.
- Port 3306: Associated with MySQL, a popular open-source relational database management system.
- Port 5432: Used for PostgreSQL, another open-source relational database system.
- Port 6660-6669: Associated with Internet Relay Chat (IRC) for chat communication.
- Port 8080: Often used as an alternative HTTP port for web servers or proxies.
- Port 9418: Used for Git, a distributed version control system.
- Port 5060: Associated with SIP (Session Initiation Protocol) for Voice over IP (VoIP) communication.
- Port 5900/5901: Used by VNC (Virtual Network Computing) for remote desktop access.
- Port 6881-6889: Commonly used by BitTorrent for peer-to-peer file sharing.
- Port 9000/9001: Used for the Tor Control Protocol, which controls the Tor network for anonymous web browsing.

- Port 5000: Used for UPnP (Universal Plug and Play) for device discovery and control.
- Port 8080: Often used as an alternative HTTP port for web servers or proxies.
Registered ports are essential for network communication, as they allow for the efficient and organized exchange of data between various services and applications. While these ports may not be as well-known as their lower-numbered counterparts, they play a crucial role in enabling a wide range of network services.
