Class
Understanding this methodology is difficult, even for customers. Therefore, let’s explain this in easier terms. The first octet
(or octets) defines the “class” (indicated by the word “net” in this example) of the address, which is the only method to tell
the size of the network (how big) and where the internet address belongs. The remaining octets indicate availability for net-
work equipment (i.e., computer or other network equipment). The three main classes are: Class A, Class B, and
Class C.
• Class A: Net, Node, Node, Node 255.0.0.0 (last three octets are available for equipment)
• Class B: Net, Net, Node, Node 255.255.0.0 (last two octets are available for equipment)
• Class C: Net, Net, Net, Node 255.255.255.0 (last octet is available for equipment)
