Example 1: Location-based subnetIn this example, we define the locations as the primary subnets. The number ofgroups required is then as follows:Number of locations:Backbone <strong>an</strong>d other infrastructure:Non-location-based networks:Future locations:Total:Three groupsOne groupOne groupTwo groupsSeven groupsThis example network would then appear as follows: If we round this up to the first power of 2, this results in eight subnets. Incorporatingthese primary subnets into the <strong>IPv6</strong> address requires 3 bits (L) (2 3 = 8; see also theappendix) This results in the following bit distribution:2001:db8:1234: L L L B B B B B B B B B B B B B ::/64This leaves 13 available bits (B).11<strong>Preparing</strong> <strong>an</strong> <strong>IPv6</strong> <strong>Addressing</strong> Pl<strong>an</strong>
