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 SEJONG NETWORKS, and 145 in South Korea. 203.231.242.81:1080 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 2743ms it is slower than the 1401ms median for South Korea proxies.
How many free proxies are on SEJONG NETWORKS
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 7 addresses on AS9848, 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.

How HProxy checks 203.231.242.81:1080
203.231.242.81:1080 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 1080: SOCKS
Port 1080 is the officially registered home of SOCKS, which forwards any kind of connection instead of only web traffic. An address offered on 1080 is being presented as a general purpose tunnel, not just a web proxy.
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 203.231.242.81:1080 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, which is how we know it spoke SOCKS5.
381 checks, 69 answered
That is 18% of the time, measured since October 7, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
203.231.242.81:1080 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).
