never answered us
IndonesiaHow this one compares
113 attempts. Not one connection.
Being published on a proxy list is a claim that an address works. It is not a test, and nobody in that chain is obliged to have tried it. We tried 113 times, which is why the answer on this page is a flat no rather than a maybe.

Each one opens a socket and waits up to 90 seconds. Slow and unreachable look identical if you stop listening early.

Most recent re-test
HProxy has opened 113 real connections to this endpoint in total. The sweep reaches every address in the database roughly once every 12 hours.
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 203.153.97.66:4153
HProxy has opened a connection to 203.153.97.66:4153 113 times and it has never once answered. That is a measurement, not an assumption, and it is the difference between this record and the lists that republished the address without testing it.
14 public sources published it
203.153.97.66 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 4153: Registered port range
This port sits in the middle range, where any ordinary program can listen without special permission. The number itself carries no reserved meaning, which tells you somebody picked it on purpose instead of accepting a default.
Every failure here was measured, not assumed
Each check opens a real connection to 203.153.97.66:4153 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. Nothing about this record is inherited from the list that published the address. 113 times HProxy tried, and 113 times the connection did not complete inside that budget, which is why the answer on this page is a flat no rather than a maybe. The handshake is attempted across HTTP, HTTPS, SOCKS4 and SOCKS5, so a proxy is never missed because we guessed the wrong protocol.
113 checks, zero connections
Not one of those 113 attempts reached a working proxy. The address stays in the database with that result attached, because "we tried 113 times and it never answered" is a far more useful answer than silence for anyone who found 203.153.97.66 somewhere and wants to know what it is.
It is still re-tested every 12 hours
203.153.97.66:4153 has never answered, and it is still in the rotation anyway. The sweep reaches every address in the database roughly once every 12 hours regardless of its history, because an address that was dark for months can be brought back online by whoever controls it without telling anybody. Its last check was on October 3, 2026, so the next one is due within a day of that. If that ever happens here, this page changes on its own.

Live free proxies right now
View allWhere this address sits
Right now our free pool holds no other free proxies on PT NettoCyber Indonesia, and 3,791 in Indonesia. 203.153.97.66:4153 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 PT NettoCyber Indonesia
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 31 addresses on AS24207, 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 203.153.97.66:4153
Is 203.153.97.66:4153 a working proxy?
Not for us. 203.153.97.66:4153 was published as a public proxy by our sources, and across 113 checks since June 14, 2026 it has never answered.
Was 203.153.97.66 ever actually a proxy?
Not while we have been watching it, which is the honest limit of what we can say. Our record opens on June 14, 2026, and across 113 checks since then it has never answered us. 14 separate lists published it as a working proxy, so it may well have answered somebody before we first tested it. We report what we measured, not what we assume.
What is the hostname for 203.153.97.66?
Its reverse DNS record is ip-66-97-static.velo.net.id. 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 203.153.97.66 hosted?
Indonesia, PT NettoCyber Indonesia (AS24207). 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 PT NettoCyber Indonesia?
None other than 203.153.97.66:4153 at the moment. AS24207 (PT NettoCyber Indonesia) has no other free proxies live in our pool right now, though that changes as we re-verify.
Are there other free proxies in Indonesia?
Yes, 3,791 free proxies are exiting from Indonesia in our pool right now, answering in 7186ms 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).
