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 5.104.81.13:8118
HProxy has checked 5.104.81.13:8118 732 times and it answered 116 of those. Every one of those was a real connection attempt, never a lookup.
43 public sources published it
5.104.81.13 appears in 43 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 8118: Privoxy default
Port 8118 is the default for Privoxy, a filtering proxy most often paired with Tor. Finding it suggests somebody built a privacy setup on purpose, rather than leaving a door open by accident.
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 5.104.81.13:8118 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.
732 checks, 116 answered
That is 16% of the time, measured since July 10, 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. 5.104.81.13:8118 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 August 30, 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.

View allWhere this address sits
Right now our free pool holds no other free proxies on Contabo Asia Private Limited, and 2,591 in Japan. 5.104.81.13:8118 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
Contabo Asia Private Limited is the 220th largest source of free proxies we have ever measured.
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 176 addresses on AS141995, which is 0.03% of every address in the database and a small corner of the database. That makes it the 220th largest source of free proxies of every network we have ever seen. None of them are answering at the moment, though every one stays in the re-check rotation in case that changes.

Questions about 5.104.81.13:8118
Is 5.104.81.13:8118 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 July 18, 2026. We still re-test it periodically in case it returns.
Was 5.104.81.13 ever actually a proxy?
Yes. We ran 732 checks against it and it answered 116 of them, about 16% of the time, over 8 days on our list.
What is the hostname for 5.104.81.13?
Its reverse DNS record is vmi3109246.contaboserver.net. That is what the address itself publishes about who operates it, which is often more telling than the network name: hosting providers name their machines by region and instance type, and a residential line usually carries its ISP's own pattern.
Where was 5.104.81.13 hosted?
Hyogo, Japan, Contabo Asia Private Limited (AS141995). It is a datacenter address, not a home connection.
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 Contabo Asia Private Limited?
None other than 5.104.81.13:8118 at the moment. AS141995 (Contabo Asia Private Limited) has no other free proxies live in our pool right now, though that changes as we re-verify.
Are there other free proxies in Japan?
Yes, 2,591 free proxies are exiting from Japan in our pool right now, answering in 1260ms at the median. If this address is not usable, that list is the place to look for a working one.

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).
