Where this address sits
Right now our free pool holds 3 other free proxies on Huawei, and 286 in Hong Kong. 159.138.24.221:3128 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 2932ms it is slower than the 1307ms median for Hong Kong proxies.
HUAWEI INTERNATIONAL PTE. LTD. is the 125th 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 424 addresses on AS136907, which is 0.05% of every address in the database and a small corner of the database. That makes it the 125th largest source of free proxies of every network we have ever seen. 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.

How HProxy checks 159.138.24.221:3128
159.138.24.221:3128 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 3128: Squid default
Port 3128 is the default for Squid, the most widely installed proxy software in the world. Most addresses published on 3128 are Squid servers that were meant to serve one office or one network and ended up reachable by everybody.
It has answered every single check
Each check opens a real connection to 159.138.24.221:3128 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. 159.138.24.221:3128 has completed that handshake on all 24 attempts so far, which is rare on a free public proxy and worth treating with some suspicion until the record is longer. The handshake is attempted across HTTP, HTTPS, SOCKS4 and SOCKS5, which is how we know it spoke HTTP and HTTPS.
24 checks, 24 answered
That is 100% of the time, measured since October 16, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
159.138.24.221:3128 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).
