  • The HTTP_CACHE_CONTROL header exists, and is non zero. This may indicate a caching proxy.
  • The header HTTP_CACHE_CONTROL includes proxy telltales.
  • The header HTTP_X_FORWARDED_FOR may include an IP address other than the one you are coming from: 10.3.139.143
  • In addition, the header HTTP_X_FORWARDED_FOR seems to be leaking a private IP address: 10.3.139.143
  • You have no reverse DNS entry. This may have been intentionally left blank as a concealment tactic.
  • The header: HTTP_X_FORWARDED_FOR is present with the value:10.3.139.143.
  • The header: HTTP_VIA is present with the value:1.1 squid-proxy-5b5d847c96-jpdts (squid/6.10).

    Reverse TTL Check (http):

    descriptionreverse ttl
    The Reverse TTL check reveals the number of hops between this server and the host making the http requests. If this differs greatly from the results of a traceroute to this server, it may be an indication that your http traffic and icmp traffic are taking separate paths.

    Form Data Behavior Check:

    No change in behavior detected when POST form data is present.
    No change in behavior detected when GET form data is present.

    File Extension Check:

    The file extension check will list any file extensions that show different behavior when requested from this server. If none are listed below, nothing was found. (Note: if your ISP is invisibly proxying everything the same way we might not find anything here.) This is currently experimental - if you get an interesting result please let me know.
