Anonymous proxy
A proxy that hides your real IP address but still identifies itself as a proxy to the sites you visit.
Anonymity grade is decided by a handful of request headers, and nothing else. When a proxy relays your request it can add fields describing where the request came from. X-Forwarded-For carries the original client address. Via names the intermediary and its protocol version. Forwarded, the standardised version from RFC 7239, packs both into one field. An anonymous proxy strips your address out of those headers but leaves at least one of them present, so the destination learns that a proxy was involved while never learning who was behind it.
That distinction is the whole point of the grade. Your address is hidden, the fact of proxying is not. A site that only wants to know whether you are in Germany is satisfied. A site that treats any declared intermediary as a reason for extra scrutiny is not, and the tell it acts on is the leftover header rather than the address itself.
This is why anonymity grade and address type are worth keeping separate in your head. Grade describes what the headers admit. Address type describes whose network the traffic appears to come from. An anonymous residential address and an anonymous datacenter address carry the same header signature and get treated very differently, because the second one is also sitting on a range the destination already distrusts.
The practical read: anonymous is enough when you are avoiding casual IP-based logging, geography checks or a rate limit keyed to your own address. It is not enough when the target is actively scoring requests for automation, because you have handed it a free signal before it even looks at behaviour.
How it works
- 1.Send a request through the proxy to any endpoint that echoes back the headers it received.
- 2.Look for your own public IP in the response. If it appears anywhere, the proxy is transparent, not anonymous.
- 3.Look for Via, X-Forwarded-For, Forwarded, X-Real-IP or Proxy-Connection. If your address is absent but one of these is present, the grade is anonymous.
- 4.If your address is absent and none of those headers appear at all, the proxy is grading elite.
How HProxy handles it
Grade is a measured property, not a claim, so we re-test it rather than trusting what a source advertises. Of the 4,023 free proxies alive in our pool when we last published the figures on 11 August 2026, 1,440 graded elite and 552 were transparent, with the remainder sitting at this middle grade. A proxy advertised as anonymous that echoes your address back is simply mislabelled, and re-checking is the only way to know which is which.
Frequently asked questions
Is an anonymous proxy actually anonymous?
It hides your address and announces that a proxy is in use, so it is anonymous in the narrow sense that the destination cannot see who you are. It is not invisible. A site that treats any declared intermediary as grounds for extra scrutiny acts on the leftover header rather than on your identity, and against those targets the grade is not enough.
What is the difference between anonymous and elite?
Only what the headers admit. Both hide your real address. An anonymous proxy leaves at least one header, Via, X-Forwarded-For, Forwarded or similar, revealing that a proxy relayed the request. An elite proxy sends none of them, so the request is shaped like an ordinary direct connection.
How do I know which anonymity grade my proxy is?
Test it rather than trust the label. Send a request through it to an endpoint that echoes back the headers it received. Your address present means transparent, absent but with proxy headers present means anonymous, and none of them present means elite. Mislabelled entries on free lists are common.
Is anonymous good enough for scraping?
It depends on what the target checks. Against sites that only care about request volume per address, yes, easily. Against anything scoring requests for automation, no, because you have handed over a free signal before behaviour is even considered. Elite is the safer default when the grade is something you can choose.
