1. Highlight, circle, or separate (whatever is easier and noticeable) each separate section of the following IPv6 addresses. Base answers on the /64 subnets.

2001:0DB8:85A3:5678:4321:ABCD:EF89:FE44

1:2:3:4:5:6:7:8

4104:FEA4:9002:5::1

4:3A:0:21:B45::423F

A::321E:45:9C:FFF:6

80FE:CAFE:123:5912::42:1

2. This question is very similar to question two except we are going to switch up the prefix i.e. /48, /52, /56. You are going to take the IP address and break it apart into the 3 sections. You can either circle, highlight, or space apart the answer.

2001:0DB8:85A3:5678:4321:ABCD:EF89:FF44 /60

5578:4782:DEDE:3434:1572:DCBA:1235:AEBB /64

11:AA:23AB:7462:5555:32:486:1 /56

1111:23:4AA:8974::3 /60

AA:BB:C:DD:E::F /64

32::4813:93:0:0:23 /52

2001:0DB8:88:149F:123:3245:AAA:B /60

3C4D:2180:4572:AFFE:CAFE:ABBC:2000:0123 /48

1282:BAFF:44:3223::4 /56

21::4523:0:0:0:2 /52

3. Lets move out of the 48-64 range; highlight just the prefix range of the next set of IP addresses.

2402:9400:0000:0000:0000:0000:0000:1111 /128

2402:9400:0000:0000:0000:0000:0000:1111 /124

2402:9400:0000:0000:0000:0000:0000:1111 /120

2402:9400:0000:0000:0000:0000:0000:1111 /116

2402:9400:0000:0000:0000:0000:1111:1111 /112

2402:9400:0000:0000:0000:0000:1111:1111 /108

2402:9400:0000:0000:0000:0000:1111:1111 /104

2402:9400:0000:0000:0000:0000:1111:1111 /100

2402:9400:0000:0000:0000:1111:1111:1111 /96

2402:9400:0000:0000:0000:1111:1111:1111 /92

2402:9400:0000:0000:0000:1111:1111:1111 /88

2402:9400:0000:0000:0000:1111:1111:1111 /84

4. Did you know you can even have odd subnets like /127, /126, /125, /123, etc..?

It may seem intimidating but its actually pretty simple.

Lets take this example IP: 2001:EF01:2345::FFFF

Next, lets take the last hextet from that IP: FFFF

Lastly, lets take out the last nibble from that hextet: F

In decimal format, what number does F represent? ___________________________________

How many binary digits do you need to represent that number? _________________________

How many numbers are between /128 and /124? _____________________________________

Piece it together yet? If not, lets break it down this way.

CIDR	End of Range	Binary Representation
/128	::	0000
/127	::1	0001
/126	::3	0011
/125	::7	0111
/124	::F	1111

Now it your turn. try and finish these ranges.

CIDR	End of Range	CIDR	End of Range
/123	::1F	/76	::F:FFFF:FFFF:FFFF
/122	::3F	/75	::1F:FFFF:FFFF:FFFF
/121		/74
/120		/73
/119		/44
/118		/43
/117		/42
/116		/41
/115		/19
/114		/18
/113		/17
