RE: [PCTECH] Private IP addresses

["Bryon Cook" <bryonc@xxxxxxxxxxx>]

I think it works like this (I am no expert!)

Class A has fewer networks (126) and more hosts (16,777,214) available
Class B has more networks (16,384) but fewer hosts (65,534) than a Class A
Class C has the most networks (2,097,152) but fewer hosts (254) than Class B

Then go to the IP Addressing Section Helper

Subject: [PCTECH] Private IP addresses

On AS400pro.com, I found the following reference:

Private IP addresses
10.x.x.x  Full Class A
172.16.x.x - 172.31.x.x  Multiple Class B addresses
192.168.x.x  Multiple Class C addresses

Can someone point me to an "easy" reference to the meanings of the
"classes", or describe them here?  I have some familiarity with the last one
as my PC at home uses a "C" address sitting behind a router/firewall, which
itself uses the IP address assigned by the ISP.  My PC at work is assigned a
class "B" address.

But what are the differences between them?
