IP Address Class A = Class B = Class C = Class D = Class E = Subnet Mask – Class A = Class B = Class C =

Public IP - A public IP address is the address that is assigned to a computing device to allow direct access over the Internet. A web server, server and any server device directly accessible from the Internet are candidate for a public IP address. A public IP address is globally unique, and can only be assigned to an unique device Private IP - A private IP address is the address space allocated by InterNIC to allow organizations to create their own private network. There are three IP blocks (1 class A, 1 class B and 1 class C) reserved for a private use.
