Is 172.67.66.28:80 a proxy? Yes.
172.67.66.28:80 is a public HTTP proxy in the HProxy free proxy list. It holds a spotty 0% uptime, and was last checked just now.
How this one compares
2 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 2 times, which is why the answer on this page is a flat no rather than a maybe.

It is not in the lifespan figures at all: those cover the 196,722 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 Cloudflare, Inc.. 172.67.66.28:80 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
Cloudflare, Inc. is the 3rd 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 22,187 addresses on AS13335, which is 3.7% of every address in the database and a substantial share of everything HProxy tracks. That makes it the 3rd 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.

How HProxy checks 172.67.66.28:80
172.67.66.28:80 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 80: HTTP
Port 80 carries ordinary web traffic, the unencrypted kind. Something answering as a proxy here is nearly always a web server configured to forward requests on to somewhere else.
Every failure here was measured, not assumed
Each check opens a real connection to 172.67.66.28:80 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. Nothing about this record is inherited from the list that published the address. 2 times HProxy tried, and 2 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.
2 checks, zero connections
Not one of those 2 attempts reached a working proxy. The address stays in the database with that result attached, because "we tried 2 times and it never answered" is a far more useful answer than silence for anyone who found 172.67.66.28 somewhere and wants to know what it is.
It is being re-tested continuously
172.67.66.28:80 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).
