Is 204.157.251.234:999 a proxy? It was listed.
204.157.251.234:999 was listed as a public proxy in 2 of our sources, but across 179 checks it never once resolved to a connectable proxy. We keep re-testing it around the clock, and it has never come online for us.
never connectable
Dominican RepublicHow this one compares
179 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 179 times, which is why the answer on this page is a flat no rather than a maybe.
0%
of 179 checks answered
Pool median 15.9%. 204.157.251.234:999 sits below it, which is ordinary for a public proxy.
179
real connection attempts
Each one opens a socket and waits up to 90 seconds. Slow and dead look identical if you stop listening early.
29
days in our records, never once answering
It is not in the lifespan figures at all: those cover the 192,073 endpoints that worked at least once before they stopped.
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 204.157.251.234:999
HProxy has opened a connection to 204.157.251.234:999 179 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.
2 public sources published it
204.157.251.234 appears in 2 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 failure here was measured, not assumed
Each check opens a real connection to 204.157.251.234:999 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. Nothing about this record is inherited from the list that published the address. 179 times HProxy tried, and 179 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.
179 checks, zero connections
Not one of those 179 attempts reached a working proxy. The address stays in the database with that result attached, because "we tried 179 times and it never answered" is a far more useful answer than silence for anyone who found 204.157.251.234 somewhere and wants to know what it is.
It is still re-tested every 24 hours
204.157.251.234:999 has never answered, and it is still in the rotation anyway. The sweep reaches every address in the database roughly once every 24 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 August 9, 2026, so the next one is due within a day of that. If that ever happens here, this page changes on its own.

Where this address sits
Right now our free pool holds 1 other free proxy on Sequre, and 40 in Dominican Republic. 204.157.251.234:999 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 SEQURE NETWORKS SRL
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 13 addresses on AS272868, which is 0.00% 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 204.157.251.234:999
Is 204.157.251.234:999 a working proxy?
No. 204.157.251.234:999 was published as a public proxy by our sources, but across 179 checks it never once resolved to a connectable proxy.
Was 204.157.251.234 ever actually a proxy?
It was listed as one, but no. 179 checks, zero successful connections. Plenty of "free proxy" lists republish addresses without ever testing them.
Where was 204.157.251.234 hosted?
Dominican Republic, SEQURE NETWORKS SRL (AS272868). 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 Sequre?
1 other free proxy is live on Sequre (AS272868) in our pool right now, alongside 204.157.251.234:999. 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 Dominican Republic?
Yes, 40 free proxies are exiting from Dominican Republic in our pool right now, answering in 5770ms 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).
