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!

A network could be considered a collection of subnets.
A subnet is a subset of a network. :-)

can you give an example of this?

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?

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 255.0.0.0 = /8
class B: first two bits are 10 in most significant byte
networks 128-191 mask 255.255.0.0 = /16
class C: first three bits in MSB are 110
networks : 192 - 223 mask 255.255.255.0 = /24
IP subnets are defined as subsets of networks
example :
subnet 10.10.100.0/24
is a subnet taken from network 10/8 by extending of 16 bits the network to host boundary.
195.22.40.0/24 this is a network and not a subnet.
200.10.0.0/23 will be a supernet : the joining of two class C major networks the opposite of a subnet
Hope to help
