Please explain to me what this guy is talking about and how do I get the info?

Here is what he emailed me.

Also, could you send me a screenshot of some information in your router. Press the print screen button to snap the screenshot to the clipboard. Go to any program that will allow you to paste an image into it. I would like to know it’s WAN Settings (public IP) ( would also like to know what Cox Cable says your IP is. I would like to see any settings on DHCP. Just basically any pertinent information regarding public or private network addresses.


Screen shot of what...?

Thanks.
