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 3 other free proxies on Ningbo Zhejiang, and 521 in China. 115.231.181.40:8128 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 1801ms it answers faster than the 2645ms median for China proxies (about 68% of it).
How many free proxies are on NINGBO, ZHEJIANG Province, P.R.China.
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 28 addresses on AS136188, which is 0.00% of every address in the database and a small corner of the database. 4 of them are answering right now, so if this particular address is not usable, the network is a reasonable place to look for one that is.

Continuous monitoring
How HProxy checks 115.231.181.40:8128
115.231.181.40:8128 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 8128: 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 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 115.231.181.40:8128 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 HTTP.
2,150 checks, 1,975 answered
That is 92% of the time, measured since July 15, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
115.231.181.40:8128 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.

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).
