Does the port prove the protocol?
No. 1080 is usually SOCKS and 8080 is usually HTTP, but a host can bind anything. Test with JoyProxy Tester or the browser extension before you trust a line from a public list.
← Tools
| Port | Usually | What it gives away | |
|---|---|---|---|
| 8080 | HTTP proxy | The default stand-in for 80. Open HTTP proxies, Squid, and many “copy this line” lists. | Open free list |
| 3128 | Squid HTTP | Squid’s factory port. Seeing 3128 on a public host often means a caching proxy was left open. | Open free list |
| 1080 | SOCKS | The SOCKS convention. SOCKS5 can carry TCP and, if the server allows it, UDP. | Open free list |
| 80 | HTTP | Plain web. A proxy on 80 is trying to look like a website, or is a gateway that also serves HTTP. | Open free list |
| 443 | HTTPS / CONNECT | TLS on the wire. Browsers expect CONNECT here; a proxy on 443 blends into ordinary HTTPS traffic. | Open free list |
| 8888 | Alt HTTP | A popular second HTTP port when 8080 is taken. Common on tiny open proxies. | Open free list |
| 4145 | SOCKS | Seen on SOCKS lists more than HTTP. Not a standard, just a habit of some public pools. | Open free list |
| 8118 | Privoxy | Privoxy’s default. Filtering HTTP proxy, often in front of Tor or another hop. | Open free list |
| 8000 | Dev HTTP | Local web servers and a few public proxies. Treat it as HTTP unless the list says SOCKS. | Open free list |
| 9050 | Tor SOCKS | Tor’s SOCKS port on the local machine. A public 9050 is almost never the Tor you think it is. | Open free list |

FAQ
About these ports
Why do free lists repeat the same ports?
Open proxies are almost always leftover defaults: Squid on 3128, Tinyproxy-style HTTP on 8888, SOCKS on 1080. The live free list re-checks what is still answering.
Should I scan these ports myself?
Only on hosts you own or are allowed to test. The free list is the public pool we already re-check. Paid Residential, Mobile, Business, ISP, and Datacenter Proxies use JoyProxy endpoints, not these well-known ports.
