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 103.99.175.54:8080
103.99.175.54:8080 has been through 1,773 checks on HProxy's list, answering 904 of them. Few addresses in the database carry a record this long.
14 public sources published it
103.99.175.54 appears in 14 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 8080: HTTP, alternate
Port 8080 is the most common proxy port on the internet. It stands in for port 80, and unlike port 80 any program can open it without administrator rights. That single detail is why so much ends up here, the deliberate and the accidental alike.
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 103.99.175.54:8080 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.
1,773 checks, 904 answered
That is 51% of the time, measured since August 8, 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. 103.99.175.54:8080 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 October 16, 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.

Where this address sits
Right now our free pool holds no other free proxies on ComSat Ltd, and 2 in Papua New Guinea. 103.99.175.54:8080 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 ComSat Ltd
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 2 addresses on AS136940, 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 103.99.175.54:8080
Is 103.99.175.54:8080 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 September 19, 2026. We still re-test it periodically in case it returns.
Was 103.99.175.54 ever actually a proxy?
Yes. We ran 1,773 checks against it and it answered 904 of them, about 51% of the time, over 42 days on our list.
What is the hostname for 103.99.175.54?
103.99.175.54 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 103.99.175.54 hosted?
Papua New Guinea, ComSat Ltd (AS136940). 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 ComSat Ltd?
None other than 103.99.175.54:8080 at the moment. AS136940 (ComSat Ltd) has no other free proxies live in our pool right now, though that changes as we re-verify.
Are there other free proxies in Papua New Guinea?
Yes, 2 free proxies are exiting from Papua New Guinea in our pool right now. 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).
