IP Addressing Schemes

One of the biggest problems is to choose the correct IP address range to use. So before we can continue with the task of allocating an address for each machine we need to be aware of some of the addressing schemes that are used.

We'll briefly describe three main schemes below. Class-based and subnetting, although still widely used, have largely been overtaken by the classless scheme known as Classless Inter-Domain Routing (CIDR), pronounced “cider.”

IP addresses have historically been based on the “class” system. For this, various classes were created: “A,” “B,” “C,” and “extended addressing mode.” “A,” “B,” and “C” were assigned a network portion and a host portion, which was a fixed value for each. An escape ...
