Proxy servers are intermediary servers that act as gateways between clients and the internet. They use specific ports for communication and routing of network traffic. Here are some commonly used proxy ports and their associated proxy protocols:
- Port 3128: Squid – Squid is a popular open-source proxy server. Port 3128 is commonly used for HTTP and FTP traffic.
- Port 8080: HTTP Proxy – Port 8080 is a general-purpose port often used for HTTP proxy servers. It’s one of the most commonly used proxy ports.
- Port 1080: SOCKS – The SOCKS proxy protocol uses port 1080 for both TCP and UDP traffic. SOCKS is a versatile protocol that can handle various types of traffic.
- Port 3124: HTTP Proxy – Another port often used for HTTP proxy servers, similar to port 3128.
- Port 8888: HTTP Proxy – Port 8888 is sometimes used for HTTP proxy servers, particularly for debugging and testing.
- Port 8118: Privoxy – Privoxy is a non-caching web proxy that uses port 8118 for HTTP traffic.
- Port 8000: HTTP Proxy – Port 8000 is occasionally used for HTTP proxy servers.
- Port 9999: WinGate – WinGate, a proxy server and NAT gateway solution, uses port 9999 for its proxy service.
- Port 5222: Jabber/XMPP – The Extensible Messaging and Presence Protocol (XMPP) can be used for proxy communication on port 5222.
- Port 808: Charles Proxy – Charles is a web debugging proxy that often uses port 808 for HTTP proxying.
These proxy ports enable organizations and individuals to control and route internet traffic, improve security, and enhance performance. The specific port used can vary depending on the proxy server software and its configuration.
