If you want to know what your public IP address is, it’s here:
207.241.237.101
There are several reasons why you would like to know this, but one reason might be that you are using a ISP that has DHCP enabled, and your IP-address changes once in a while. Another might be if you are on a private network behind a firewall and/or proxy.
The IP address above is fetched via the REMOTE_ADDR value in the $_SERVER variable with the Exec-PHP 2.0 WordPress plugin.
