Where this address sits
Right now our free pool holds 10 other free proxies on Hetzner, and 306 in Germany. 2.28.31.215:3129 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
How many free proxies are on HETZNER-AS
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 4,377 addresses on AS24940, which is 0.74% of every address in the database and a meaningful pocket of the database. That makes it the 14th largest source of free proxies of every network we have ever seen. 11 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 2.28.31.215:3129
2.28.31.215:3129 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 3129: Squid, second instance
Port 3129 is Squid's second port. When an address is already serving Squid on 3128, this is where the second instance normally sits.
Every failure here was measured, not assumed
Each check opens a real connection to 2.28.31.215:3129 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. 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 2.28.31.215 somewhere and wants to know what it is.
It is being re-tested continuously
2.28.31.215:3129 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).
