I had a smart (but non-technical) user ask me today:
Why did they pick 192.168.. for a private network address?
The only answer I could come up with is because 192 = 11000000 in binary. And 168 is 10101000 in binary. Both of which are kind of cool looking.
Is there a real historical reason for that particular choice of numbers? Why not 127.127..? Or 128.128..?
