How this one compares
Ordinary on uptime, and here is what ordinary means.

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 1 other free proxy on ONT De, and 179 in Mexico. 45.188.76.100:999 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 4251ms it is slower than the 3546ms median for Mexico proxies.
How many free proxies are on ONT NETWORKS SA de CV
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 15 addresses on AS265608, which is 0.00% of every address in the database and a small corner of the database. 2 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 45.188.76.100:999
45.188.76.100:999 is in the live pool right now, and it stays there only for as long as it keeps answering.
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 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 45.188.76.100:999 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. 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.
2,764 checks, 247 answered
That is 9% of the time, measured since June 23, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
45.188.76.100:999 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).
