Different ports can be used, depending on the proxy type and authorization chosen.
Semi-ISP, ISP, Semi-dedicated, and Dedicated Proxies
Customers can use port 3128 for HTTP connectivity and port 1080 for SOCKS connectivity with IP authorization. If using username/password authorization, the port numbers are 4444 for HTTP and 1081 for SOCKS connectivity.
In certain cases, some ISPs may block specific ports, causing the proxy to not function properly. In such instances, customers can use port 80 for "Via IP" authorization and port 8000 for "Username/Password" authorization. It is important to note that port 80 and port 8000 serve as alternative HTTP ports for the "Via IP" and "Username/Password" authorization types, respectively.
Rotating Proxies
Customers will receive a single IP address with different port numbers after a successful purchase. (See How to authorize rotating proxies?)
IPv6 Proxies
IPv6 proxies, like our rotating proxies, also use a single IP address during configuration. Real IPs are tunneled over via port 4444. (See How does your authorization scheme work for IPv6 proxies?)
Residential Proxies
Residential proxies utilize port 8000 for user/pass and 8001 for IP authorization.
