ShowIP
Now this little tool is what I was referring to before when I was speaking about being able to resolve issues quickly while over the phone and not wanting to take ages to do the smallest tasks. This little tool will show you the IP address of any webpage you are currently viewing. It will display in red on the bottom right corner. Not only that but if you left or right click it will give you a list of handy little tools at your finger tips. You can do a WHOIS lookup, traceroute, ip2country etc. This will save you a lot of time!
HeaderSpy
This one is similar to ShowIP, except it actually shows you the Server headers instead of the IP address and domain information. In fact having both is the best as you get all the info you need right there and then. A right-click will also open up some more options for further investigating. Now how is this useful you might ask? Well first of all it gives you a quick glimpse as to what OS this system is using, and any sort of modules that may be installed. The example below is of my server, which simply shows the Apache version and the OS distro name. If you use this while viewing a site on a windows machine it will say something like Microsoft/IIS6.0.
