Alongside the 40 answering right now, these addresses are in our free proxy database and are not responding at the moment. We do not delete them and we do not stop: every one is re-tested on a permanent cycle, and any of them can come back into the live list the moment it answers again. Between them they have responded 49 times across 1,159 checks we have run, the most recent of them answering 19 days ago. Open any endpoint for its full history.

About these port 21 proxies
These are public proxies gathered from across the web and continuously re-verified by HProxy's engine. They're free and fine for quick, low-stakes tasks. But like all public proxies they're shared, go down without warning, and are often already blocked by major sites. Always test before you rely on one.

Free proxies on port 21 are public proxy servers that accept connections on that specific port. This page keeps a live-checked list of them: every entry was seen answering on port 21 and re-verified continuously for uptime, speed and anonymity, so what you copy is current rather than a stale dump republished from somewhere else.
A port number is just the door a service listens behind, so what matters on this page is measurement rather than convention: the breakdown above shows how many proxies answer on port 21 right now, which protocols they speak and where they exit. Ports without a famous default service still accumulate proxies through software defaults, port-forwarding habits and the lists that republish them.
What is port 21?
A port is the numbered door a connection knocks on: an address like 203.0.113.9:21 means "this machine, door 21". Ports 0 to 1023 are reserved for well-known services and need elevated privileges to bind; everything above is open territory, which is where most proxy software lives. Our database records every ip:port pair separately because each one is genuinely a separate endpoint.
How to use a port 21 proxy
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 21 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.
Free port 21 proxies vs paid proxies
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 21 list for what it is good at and reach for paid the moment a task has to succeed.
Frequently asked
What are port 21 proxies?
Public proxy servers that accept connections on port 21. This page lists the ones currently in the HProxy pool that answered on that port at their last live check, with protocol, country, latency and uptime for each.
Why do so many free proxies use port 21?
Mostly software defaults and habit: proxy servers ship with a port picked by their authors, operators forward what is memorable, and public lists then keep re-testing the ports they already know. The population on this page is what that process has produced on port 21.
Are these port 21 proxies free?
Yes. Everything listed is free to copy and use, no signup. Free means shared and unstable, so verify an entry right before you rely on it.
How often is this list updated?
Continuously. Every endpoint is re-verified on a rolling cycle; an address that stops answering moves out of the live list into the permanent record, and returns the moment it answers again.
Is it safe to use a proxy on port 21?
The port does not change the trust question: any public proxy is operated by someone you have no agreement with. Keep logins, payments and anything private off free proxies on every port; use them for low-stakes lookups and testing.
Upgrade to the paid network
Need pools that stay clean?
Free IPs are shared and rotate out fast, so success rates swing. The paid network gives you dedicated-clean pools that hold up under load.
About this list & IP removal
Every proxy here is aggregated from publicly available sources. We do not scan or collect these IP addresses ourselves: we verify entries that are already public (live status, latency, uptime) and store nothing else about the devices behind them. The list is provided as-is, with no warranty, for lawful use only, on the basis of our legitimate interest in a free, transparent proxy directory (Art. 6 (1) (f) GDPR). Never route passwords or sensitive data through a public proxy. If an IP address is yours and you'd like it removed, email legal@hproxy.com and we'll take it down (Art. 21 GDPR).
