A few years back when starting a new role providing 3rd Level support for an international network with over one hundred devices in my remit, it became apparent very quickly I was going to struggle to remember all the IP addresses in a few days or even the host names for that matter. There was no standard tools being use to connect all the devices, Windows XP telnet seem to be the tool of choice.
Most of the devices had some standards naming conventions. Like site code and type of device. So Lon_SW1 would be switch 1 in London. I decided to dust of my scripting skills and make life easier for myself.
