Where this address sits
Right now our free pool holds 3,788 other free proxies on Amazon, and 2,624 in Japan. 18.183.174.103:8254 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 764ms it answers faster than the 1218ms median for Japan proxies (about 63% of it).
Amazon.com, 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 35,458 addresses on AS16509, which is 4.9% 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. 3,789 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 18.183.174.103:8254
18.183.174.103:8254 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 8254: 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.
It has answered every single check
Each check opens a real connection to 18.183.174.103:8254 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. 18.183.174.103:8254 has completed that handshake on all 11 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 and SOCKS4 and SOCKS5.
11 checks, 11 answered
That is 100% of the time, measured since August 30, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
18.183.174.103:8254 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.

What kind of proxy is 18.183.174.103?
It speaks HTTP, HTTPS, SOCKS4, SOCKS5, and our checks grade it anonymous. The port is 8254. Point your client at 18.183.174.103:8254 over http to route a request through it.
Where is 18.183.174.103 located?
Traffic through it exits from Tokyo, Japan, on Amazon.com, Inc. (AS16509). That is where the destination site will think your request came from.
How fast is 18.183.174.103:8254?

Is it safe to use 18.183.174.103:8254?
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.
How many free proxies are on Amazon?
3,788 other free proxies are live on Amazon (AS16509) in our pool right now, alongside 18.183.174.103:8254. 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.
18.183.174.103:8254 has answered 100% 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.

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).
