It worked sometimes, for 58 days, and then it stopped.
Every free proxy list quotes an uptime figure. Almost none of them tell you what a normal one looks like, so here is ours: across the 5,626 proxies answering right now, the middle of the pack answers 27% of the checks we send it.

What normal looks like
Every number above is measured against these two.
A percentage on a proxy list means nothing without the shape of the thing it came from. These are the two distributions the rest of this page compares against, drawn from HProxy's own checks rather than from anybody's marketing page.

How HProxy checks 38.51.243.193:999
HProxy has checked 38.51.243.193:999 494 times and it answered 69 of those. Every one of those was a real connection attempt, never a lookup.
19 public sources published it
38.51.243.193 appears in 19 of the public proxy sources HProxy tracks. Lists copy from each other constantly, so an address showing up in many of them says a lot about how widely it was republished and very little about whether it ever worked.
Port 999: System port
Ports below 1024 are protected. On most systems you need administrator rights to open one at all. So whatever is answering here was set up by someone with full control of that machine, not by some ordinary program that happened to be running.
Every check is a real connection
HProxy does not read this address off somebody else's list and pass it on. Each check opens a real connection to 38.51.243.193:999 and gives it up to 90 seconds to answer. Slow is not the same as unreachable, and plenty of working proxies take half a minute to reply. Anything that does not answer in that budget counts as a failure and is recorded as one, which is why the percentage on this page moves rather than sitting at a marketing number. The handshake is attempted across HTTP, HTTPS, SOCKS4 and SOCKS5, so a proxy is never missed because we guessed the wrong protocol.
494 checks, 69 answered
That is 14% of the time, measured since June 18, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
We are still watching for it to come back
Being archived does not stop the testing. 38.51.243.193:999 answered before, so it is exactly the kind of address that can return, and the sweep works through the whole database and reaches every address roughly once every 12 hours. Its last check was on September 12, 2026, so the next one is due within a day of that. The moment it answers again it is promoted straight back into the live free proxy list, automatically, with no manual step.

Live free proxies right now
View allWhere this address sits
Right now our free pool holds no other free proxies on Intercomm DE, and 450 in Colombia. 38.51.243.193:999 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
How many free proxies are on INTERCOMM DE NARINO SAS
Open proxies cluster rather than spreading evenly across the internet. Hosting providers and cloud platforms run enormous numbers of near-identical servers, so a handful of networks end up carrying a disproportionate share of every public proxy list, including ours. HProxy tracks 14 addresses on AS272869, which is 0.00% of every address in the database and a small corner of the database. None of them are answering at the moment, though every one stays in the re-check rotation in case that changes.

Questions about 38.51.243.193:999
Is 38.51.243.193:999 a working proxy?
No, not any more. It was a working public proxy in HProxy's free pool and has since gone dark, last answering on August 15, 2026. We still re-test it periodically in case it returns.
Was 38.51.243.193 ever actually a proxy?
Yes. We ran 494 checks against it and it answered 69 of them, about 14% of the time, over 58 days on our list.
What is the hostname for 38.51.243.193?
38.51.243.193 publishes no reverse DNS record. That is not unusual and it is not suspicious on its own, but it does mean the address volunteers nothing about who runs it, so the network and the check history below are all there is to go on.
Where was 38.51.243.193 hosted?
Tuquerres, Narino, Colombia, INTERCOMM DE NARINO SAS (AS272869). It is a residential or ISP address rather than a datacenter one.
Why keep a page for an address that no longer works?
Because "was this address ever a proxy, and when" is a real question. If you are looking at this IP in a firewall log or an abuse report, the dates and the check counts here are the answer. HProxy's public proxy IP list keeps every address it has ever tracked and carries on re-testing them, so deleting this record would throw all of that away.
How many free proxies are on Intercomm DE?
None other than 38.51.243.193:999 at the moment. AS272869 (Intercomm DE) has no other free proxies live in our pool right now, though that changes as we re-verify.
Are there other free proxies in Colombia?
Yes, 450 free proxies are exiting from Colombia in our pool right now, answering in 5068ms at the median. If this address is not usable, that list is the place to look for a working one.

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).
