How this one compares
49 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 49 times, which is why the answer on this page is a flat no rather than a maybe.
0%
of 49 checks answered
Pool median 16.4%. 104.129.194.43:10999 sits below it, which is ordinary for a public proxy.
49
real connection attempts
Each one opens a socket and waits up to 90 seconds. Slow and dead look identical if you stop listening early.

days in our records, never once answering
It is not in the lifespan figures at all: those cover the 192,781 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.

Where this address sits
Right now our free pool holds no other free proxies on Zscaler, and 934 in United States. 104.129.194.43:10999 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
ZSCALER, INC. is the 69th 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 671 addresses on AS22616, which is 0.11% of every address in the database and a meaningful pocket of the database. That makes it the 69th 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.

Continuous monitoring
How HProxy checks 104.129.194.43:10999
104.129.194.43:10999 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 10999: 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 104.129.194.43:10999 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. 49 times HProxy tried, and 49 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, which is how we know it spoke HTTP.
49 checks, zero connections
Not one of those 49 attempts reached a working proxy. The address stays in the database with that result attached, because "we tried 49 times and it never answered" is a far more useful answer than silence for anyone who found 104.129.194.43 somewhere and wants to know what it is.
It is being re-tested continuously
104.129.194.43:10999 is in the live rotation, so it is re-tested continuously rather than on a daily cycle. If it stops answering it is marked down immediately, and if it stays down for 3 days it moves into the public proxy database with its full record intact. Nothing is deleted at any point.

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).
