network and subnets

Hi all, when talking about networks, what would we call a network and what would a subnet be classed as, people seem to use these terms on different meanings!


Re: network and subnets

A network could be considered a collection of subnets.

A subnet is a subset of a network. :-)

Re: network and subnets

can you give an example of this?

Re: network and subnets

An example would be:

The internet is a huge network

Within that network are multiple block of addresses

Think of it like a neighborhood. Neighborhood's consist of multiple houses.

The neighborhood is the network, and the multiple houses are you subnets.

Does that help?

Re: network and subnets

Hello Carl,

in ip addressing scenario the terms are:

networks or major networks are the classic A,B, C networks

class A: first bit is 0 in Most significant byte

networks 1-126 mask = /8

class B: first two bits are 10 in most significant byte

networks 128-191 mask = /16

class C: first three bits in MSB are 110

networks : 192 - 223 mask = /24

IP subnets are defined as subsets of networks

example :


is a subnet taken from network 10/8 by extending of 16 bits the network to host boundary. this is a network and not a subnet. will be a supernet : the joining of two class C major networks the opposite of a subnet

Hope to help
