How this one compares
It worked sometimes, for 6 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 3,424 proxies answering right now, the middle of the pack answers 15.9% of the checks we send it.
1%

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

Of the 192,073 free proxies we have watched stop working, half were gone within 28 days of us first seeing them.
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 103.66.233.161:4145
HProxy has checked 103.66.233.161:4145 313 times and it answered 2 of those. Every one of those was a real connection attempt, never a lookup.
18 public sources published it
103.66.233.161 appears in 18 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 4145: SOCKS4, common
Port 4145 is everywhere in free proxy lists, nearly always as SOCKS4. No standards body ever gave it that job. It stuck because everyone copied everyone else, so treat the number as a strong hint rather than a promise.
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 103.66.233.161:4145 and gives it up to 90 seconds to answer. Slow is not the same as dead, 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.
313 checks, 2 answered
That is 1% of the time, measured since June 14, 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. 103.66.233.161:4145 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 24 hours. Its last check was on August 9, 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 1 other free proxy on NET 4, and 688 in India. 103.66.233.161:4145 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 NET 4 U SERVICES PVT 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 43 addresses on AS134014, which is 0.01% of every address in the database and a small corner of the database. 1 of them is answering right now, so if this particular address is not usable, the network is a reasonable place to look for one that is.

Questions about 103.66.233.161:4145
Is 103.66.233.161:4145 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 June 20, 2026. We still re-test it periodically in case it returns.
Was 103.66.233.161 ever actually a proxy?
Yes. We ran 313 checks against it and it answered 2 of them, about 1% of the time, over 6 days on our list.
Where was 103.66.233.161 hosted?
India, NET 4 U SERVICES PVT LTD (AS134014). 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 NET 4?
1 other free proxy is live on NET 4 (AS134014) in our pool right now, alongside 103.66.233.161:4145. Networks that host one open proxy usually host several, which is why the whole AS is worth browsing rather than just this address.
Are there other free proxies in India?
Yes, 688 free proxies are exiting from India in our pool right now, answering in 1513ms 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).
