Proxy anonymity checkerelite, anonymous or transparent?

Paste it above and run the check. For every proxy that answers on HTTP, the tool reads the headers the proxy forwarded to a server we control and grades it elite, anonymous or transparent. That is the only way to know your anonymity level, because it depends on what the proxy actually sends, not on what it claims.

Three levels of how much a proxy gives away. Elite forwards no proxy headers at all, so the site sees an ordinary visitor. Anonymous hides your real IP but sends a header admitting a proxy is involved. Transparent forwards your real IP, which defeats the purpose. For almost every use case you want elite.

Through headers it adds to your request. X-Forwarded-For, Via, X-Real-IP and a handful of others are meant to record the path a request took, and a transparent proxy writes your real address straight into one of them. The site reads it and knows exactly who you are, proxy or not. This checker looks for every one of those headers.

Elite, for anything where being seen as a proxy is a problem: account work, ad verification, price scraping on defensive targets. Anonymous is fine for ordinary pages that do not punish the mere presence of a proxy. Transparent is only useful as a plain cache and should be filtered out of anything privacy related.

SOCKS4 and SOCKS5 do not add the forwarding headers that give an HTTP proxy away, so they tend to grade well, but it still depends on the specific proxy and its operator. This checker grades SOCKS proxies the same way it grades HTTP ones, so you never have to assume.

Headers are only one signal. Elite means the proxy leaks nothing at the header level, which closes the easiest and most common way to be spotted, but a site can also weigh the network the address sits on. A datacenter range flagged as hosting is a giveaway no header hides, which is why the checker reports the network beside the anonymity grade.
