Q33Advanced Addressing and Routing Solutions
A company intends to migrate to IPv6. It will associate its IPv4 addresses with the least significant bits of the new IPv6 addresses. A network administrator whose employee ID is `4264:42:116` is preparing a mapping scheme for the new IPv6 addresses. To which address does the `172.16.10.0/24` network map?

A: IPv6 Address Allocation Fully Linked to IPv4
5
I think A: ac10:a00 = 172.16.10.0 and /120 = /24
A 4
Selected Answer: A
" link their IPv4 addresses to the lowest significant bits "
THis can never be a /64 network but must be a /120 network.
A 4
Selected Answer: A
172 = 1010|1100 = AC
016 = 0001|0000 = 10
010 = 0000|1010 = 0A
000 = 0000|0000 = 0
/120 = 256 IPs in IPv6 which is equal to a /24 in iIPv4
D 2
Selected Answer: D
Answer would have to be D based on the binary to hex conversion 10 = 0a in hex and the only option that matches this is D.

Correct B

Nevermind. A looks right. Didn't notice the leading 0 is missing in A.
A 1
Selected Answer: A
".... IPv4 addresses to the lowest significant bits of the new Ipv6 addresses". Lowest significant bits is the key phrase here. You will need to place the hex-converted IPV4 address at the end, with 8 bits left for host addressing (equivalent of /24 IPV4).

Ignore the employee ID in the questions. They're only there to add useless info and confuse you,
