How this one compares

Reliable enough to sit in the better half of everything we are watching.

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 2,158 other free proxies on Amazon, and 514 in Japan. 43.206.240.252:18255 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 693ms it answers faster than the 859ms median for Japan proxies (about 81% of it).

Amazon.com, Inc. is the 2nd 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 26,095 addresses on AS16509, which is 4.4% of every address in the database and a substantial share of everything HProxy tracks. That makes it the 2nd largest source of free proxies of every network we have ever seen. 2,159 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 43.206.240.252:18255

43.206.240.252:18255 is in the live pool right now, and it stays there only for as long as it keeps answering.

  1. Port 18255: 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.

  2. 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 43.206.240.252:18255 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, which is how we know it spoke HTTP.

  3. 208 checks, 36 answered

    That is 17% of the time, measured since August 7, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.

  4. It is being re-tested continuously

    43.206.240.252:18255 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).
