I'm working through a Microsoft Academic tutorial on Win7 configuration and I'm instructed to run ipconfig/all at cmd prompt. Then I'm asked where the information displayed came from. You know, that's a good question! I would guess that ipconfig/all looks at information stored and pings the network for the attached device information but I don't know that for sure and certainly can't give a citation even if it is right. So... where does the info in response to an ipconfig.all command come from and where can I find a citation to validate the info?
