Youre the head network administrator for a large manufacturi

You’re the head network administrator for a large manufacturing enterprise that’s completing its support for IPv6. The company has six major locations with network administrators and several thousand users in each location. You’re using a base IPv6 address of 2001:DB8:FAB/48 and want network administrators to be able to subnet their networks however they see fit. You also want to maintain a reserve of address spaces for a possible 6 to 10 additional locations in the future. Each network administrator should be able to construct at least 200 subnets from the addresses you supply, and each location should have the same amount of available address space. What IPv6 addresses should you assign to each location? When constructing your answer, list each location as Location 1, Location 2, and so forth.

Solution

The base IPV6 adress is given as :2001:0db8:0fab:0000:0000:0000:0000:0000/48
Last 16 its of prefix ID i.e.0fab thus the
prefix ffff:ffff:ffff:0000:0000:0000:0000:0000
AS said, the subnets should allow atleast upto 10 i.e(6 exixting+10=16).calculatig for 10 subnets .
To get at least 16 new subnets divide 2001:db8:fab::/48 into 16 new subnets.
Each of these subnets is a /52 containing 4096 /64s. The new subnets are as follows:
Location 1:2001:db8:fab::/52
Location 2:2001:db8:fab:1000::/52
Location 3 :2001:db8:fab:2000::/52
Location 4: 2001:db8:fab:3000::/52
Location 5: 2001:db8:fab:4000::/52
Location 6: 2001:db8:fab:5000::/52

And said that each Location -200 subnets.
take for Location 1:db8:fab::/52
To get at least 200 new subnets divide 2001:db8:fab::/52 into 256 new subnets. Each of these subnets is a /60 containing 16 /64s
i.e.new will be like:2001:db8:fab::/60,2001:db8:fab:10:/60,2001:db8:fab:20:/60 so on
