Where this address sits
Right now our free pool holds 40 other free proxies on Viettel, and 435 in Vietnam. 171.232.51.177:5000 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 1641ms it answers faster than the 1911ms median for Vietnam proxies (about 86% of it).
Viettel Group is the 13th 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 7,187 addresses on AS7552, which is 0.78% of every address in the database and a meaningful pocket of the database. That makes it the 13th largest source of free proxies of every network we have ever seen. 41 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 171.232.51.177:5000
171.232.51.177:5000 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 5000: 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.
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 171.232.51.177:5000 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. 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 SOCKS4 and SOCKS5.
13 checks, 12 answered
That is 92% of the time, measured since October 15, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
171.232.51.177:5000 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.

Is it safe to use 171.232.51.177:5000?
Treat it the way you would any public proxy: it is operated by someone we have no relationship with, it is shared with strangers, and anything you send unencrypted over it can be read. Fine for a quick geo check or a scrape of public data, never for logins, payments or anything private.

40 other free proxies are live on Viettel (AS7552) in our pool right now, alongside 171.232.51.177:5000. Networks that host one open proxy usually host several, which is why the whole AS is worth browsing rather than just this address.

Where to go next
Upgrade to the paid network
This one is good, and it will still disappear.
171.232.51.177:5000 has answered 92% of our checks, which puts it well above most of what we track. It is still a public endpoint with nobody standing behind it: nobody agreed to serve you, no capacity is set aside for you, and there is no warning on the day it stops. Fine for a test, a bad foundation for anything that has to work tomorrow.

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).
