I know. If you'd fully read my original post, you'd see that I know that this is an internal private block. What I'm wondering is how linux.com is able to see the internal IP address of the poster? Normally, when a webserver sees the remote ip of a client that is behind a NAT, it sees the external gateway IP, not the internal IP. So how is linux.com able to see the internal IP? It seems like they are able to do this on several other posts too.
I think Squid and some caching proxies can add a header called X-Forwarded-For or something like that, but I'm not sure how widely used that is.
