IPv6

1. Given the following IPv6 address: 2008:0000:05A3:0000:0000:00FB:0C7A:FE29/64. Simply the address to be optimal in IPv6 (rewrite the address to be the shortest possible IPv6 equivalent address). Explain what you did. (10 points)

2008:0000:05A3:0000:0000:00FB:0C7A:FE29

Step 1: Omit leading Zeros

The first thing to do is to omit the leading zeros in the address.

2008:0000:05A3:0000:0000:00FB:0C7A:FE29

So after taking out the leading zeros. The address will look like this.

2008:0:5A3:0:0:FB:C7:FE29

Step 2: Compress consecutive zeros

So to compress this further. Have to see where there are consecutive zeros. Which there is, there are two consecutive zeros around the middle of the address

2008:0:5A3:0:0:FB:C7:FE29

So to omit the consecutive zeros, have to replace them with a double colon. Once removed and replace with a double colon. The address in compress form would be. Also the double colon can only be used once per address.

2008:0:5A3::FB:C7:FE29

Note: The reason why the first and only zero with no other character is omitted is because it doesn’t have any consecutive zeros behind it.

2. Given the diagram below. Assume the IPv6 prefix is 2005:007D:4500:000C::/64. Find the IPv6 EUI addresses for computers A and B. Show all your work. Do not just copy and paste the final answer to avoid losing points. (20 Points)

Computer A’s IPv6 EUI Address is: ::210:11FF:FEDA:6E71

This is how I got the answer:

Computer A : 00-10-11-D8-6E-71

- Step 1: Convert to Binary and add FF and FE in the middle

- Step 2: Convert Binary to Hexadecimal and replacing the first 7 bits with a 1

- Step 3: Take write out the EUI-64 address and compress it (if need be)

::0210:11FF:FED8:6E71

- Omit the leading zeros:

::210:11FF:FED8:6E71

- Computer B’s IPv6 EUI Address is: ::202:4AFF:FE5C:E1C9

This is how I got the answer:

Computer B: 00-02-4A-5C-E1-C9

- Step 1: Convert to Binary and add FF and FE in the middle

- Step 2: Convert Binary to Hexadecimal and replacing the first 7 bits with a 1

- Step 3: Take write out the EUI-64 address and compress it (if need be)

::0202:4AFF:FE5C:E1C9

- Omit the leading zeros:

::202:4AFF:FE5C:E1C9

3. The following IPv6 prefix, 2009:0000:00AF::/48, was assigned to ABC Corporation. You are required to subnet the given network to use a /64 subnet mask. Find the first 15 IPv6 subnets. List the subnets below, one subnet per line. (15 points)

2009:0: AF: 1:: /64

2009:0: AF: 2:: /64

2009:0: AF: 3:: /64

2009:0: AF: 4:: /64

2009:0: AF: 5:: /64

2009:0: AF: 6:: /64

2009:0: AF: 7:: /64

2009:0: AF: 8:: /64

2009:0: AF: 9:: /64

2009:0: AF: a:: /64

2009:0: AF: b:: /64

2009:0: AF: c:: /64

2009:0: AF: d:: /64

2009:0: AF: e:: /64 2009:0: AF: f:: /64
