2 - Subnetting Table:
=====================

	Major IP space:		192.168.0.0 / 22

	Step 1 - The limits of the major IP space:
	------------------------------------------

	192.168.0.0 / 22	[N: 192.168.0.0 - 192.168.3.255 :B]


	Step 2 - Subnet the major IP space into smaller networks based on requirements:
	-------------------------------------------------------------------------------

LAN		LAN		Network		Broadcast	First usable	Last usable	Subnet
Name		Subnet		Address		Address		IP		IP		Mask
--------------------------------------------------------------------------------------------------------------
LAN1 (300 H)	192.168.0.0/23	192.168.0.0	192.168.1.255	192.168.0.1	192.168.1.254	255.255.254.0
LAN2 (120 H)	192.168.3.0/25	192.168.3.0	192.168.3.127	192.168.3.1	192.168.3.126	255.255.255.128
LAN3 (200 H)	192.168.2.0/24	192.168.2.0	192.168.2.255	192.168.2.1	192.168.2.254	255.255.255.0

	Step 3 - Checking fitness:
	--------------------------

	Condition: last allocated IP (the broadcast address of the last allocated LAN) must be less or equal to the major IP space's broadcast address.

	In this case:	192.168.3.127 <= 192.168.3.255.
	Is it ?
		-> if Yes:	OK
		-> if No:	We have a problem. We either reorganize our networks or we increase the space on the major IP space.
