This page offers suggestions on how one might determine the '''IP''' address associated with a particular system.

There are many ways in which one can

== For Scripting ==

The following '''URL'''s will return your '''IP''' address (as you appear to the Internet) as a simple text string:

* http://whatismyip.org/
* http://nst.sourceforge.net/nst/cgi-bin/ip.cgi
* http://www.networksecuritytoolkit.org/nst/cgi-bin/ip.cgi
* http://www.univstech.com/nst/cgi-bin/ip.cgi

The following '''bash''' script fragment demonstrates how one can retrieve the Internet '''IP''' address and store it in a variable:

<pre class="programListing">

# Use wget to retrieve the IP address
IP_ADDRESS="$(wget -O - http://nst.sourceforge.net/nst/cgi-bin/ip.cgi 2>/dev/null)";

</pre>

The '''[http://nst.sourceforge.net/nst/docs/scripts/getipaddr.html getipaddress]''' script uses this basic technique and adds error checking, caching and the ability to use multiple sources (should a server be down). The following demonstrates how one would achieve similar results using the '''--public-address''' option provided by the '''getipaddr''' script:

<pre class="programListing">

# Use getipaddress to retrieve the IP address
IP_ADDRESS="$(getipaddr --public-address)";

</pre>
