Free port 3128 proxies 2026

The default listening port of Squid, the most widely deployed open-source caching proxy. In proxy terms the port is half of every endpoint you copy from this page: an address like 203.0.113.9:3128 means "this machine, this door". The same machine can run different services on other ports, which is why our database records every ip:port pair separately.

Copy an entry from the table and set the IP and port in your browser's proxy settings or your HTTP client, matching the protocol the list shows for it. The port is not optional: the same IP without 3128 points at nothing. Test against a page that echoes your address before trusting it with real work, and click any IP for its full record.

Free proxies churn whatever port they sit on, so pull several candidates and rotate. If a firewall sits between you and the internet, note that unusual ports are exactly what restrictive networks block first; proxies on 443 or 80 travel furthest.

Everything here is free, public and shared, which is fine for testing, research and one-off checks. The trade-off is the same on every port: no uptime promise, unpredictable speed, and neighbours you cannot choose.

HProxy's paid residential, ISP, mobile and datacenter proxies run on stable infrastructure with clean IPs, billed by the gigabyte with no subscription. Keep the free port 3128 list for what it is good at and reach for paid the moment a task has to succeed.
