Hm, for me, a network interface has an ip address, not a user.

Google: "identifying the other end of a socket"

If you by "read" mean "find out what it is", and assuming you run a CGI
script, you may be looking for the environment variable $ENV{REMOTE_ADDR}.

What kind of internet connection?

There are different answers, depending on how the connection comes
in to your server. HTTP, FTP, TELNET, SSH, BitTorrent, Skype, etc, etc, etc.

actually from the tcp/ip perspective those are all the exact same
thing. sockets are sockets and you can get all the IP info you want
about a peer socket. the difference you claim is in the data protocol
that runs on top of the socket layer (including any encryption).

Hi,

(\d)\.(\d)\.(\d)\.(\d)

represents the ipaddress.

66.94.234.13 is a valid IP address which won't be matched by that pattern.

You should at least mention Regexp::Common if you're correcting an IP
address pattern. I know the original question was not about that, but
it's still better to make a useful reply than just to point out a
counter-example.
