Is 233.221.176.229:80 a proxy?
No.
233.221.176.229 is not a public internet address at all. 224.0.0.0/4 is multicast: these addresses name a GROUP of listeners rather than a single host. A proxy needs to be one machine you open a TCP connection to, which a multicast group is not.

Questions about 233.221.176.229:80
Is 233.221.176.229:80 a proxy?
No — this address cannot be a proxy. 224.0.0.0/4 is multicast: these addresses name a GROUP of listeners rather than a single host. A proxy needs to be one machine you open a TCP connection to, which a multicast group is not.
Then why does 233.221.176.229 show up in free proxy lists?
Because most public lists republish whatever they scrape without ever opening a connection to it. Addresses like this one get copied from list to list for years. HProxy did test it, which is exactly why it sits in our database with no successful connections rather than being presented as usable.
I found 233.221.176.229 in my logs — what does that mean?
Not that someone proxied through it. Multicast addresses are meaningful only inside the machine or network that used them, so the same address appears in millions of unrelated logs. If you are tracing real traffic, the useful identifier will be elsewhere in the request.

Need pools that stay clean?
Free IPs are shared and rotate out fast, so success rates swing. The paid network gives you dedicated-clean pools that hold up under load.
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 [email protected] and we'll take it down (Art. 21 GDPR).
