Internet Addressing
The Basics
Every machine on the Internet has its own unique Internet Protocol (IP)
address. This address is a series of four 8-bit numbers (0-255)
separated by periods. Your current IP address is
3.94.129.211. This number, although unique, is not
the easiest thing in the world to remember; therefore, most Internet
machines have this number aliased to an easier-to-remember name. This
is called your host name. Your current host name is ec2-3-94-129-211.compute-1.amazonaws.com (this may be the name of your proxy server if you
go through that).
How It Works
Our web page simply displays this information.
With each web request, the server obtains a lot of useful information
regarding what machine you're coming from, what page you're coming from,
etc. It needs this information to know where to send web pages. Our
server, the Apache server, allows
us to access these variables and echo them to the web page. For those
people using a proxy server, our server also collects the host name
that is being proxied (which is what is under "Proxied For:"). You
shouldn't be concerned that this information is available as that's the
nature of how the Internet works. However, knowing that your
information is available freely on the Internet, you should take
precautions to make sure that your system is closed to outside access
attempts. This may mean installing service packs or updates for your
operating system and making sure that server software that you run is
accessible only to those people who you trust.
What Texas.Net Uses This Information For
Texas.Net collects the information from the web server for a few uses
other than just letting you know your IP address and host name. For
form submissions, Texas.Net also sends along the host name of the
person sending the e-mail to determine whether the source may be the
cause of a problem or in case someone abuses the system. The
information also allows us to lock out non-Texas.Net customers from
using some scripts on our system. However, beyond that, not much can be done with the information.
