Compress the 2001:0DB8:0000:C030:0000:0000:09A0 address.

A2001:DB8:0:C030::9A0

Show Suggested Answer

Suggested Answer: A

To compress the IPv6 address 2001:0DB8:0000:C030:0000:0000:09A0, the following rules are applied:

Remove leading zeros in each hextet (e.g., 0DB8 becomes DB8).

Replace contiguous blocks of zeros with :: (only once in the address).

Thus, the compressed form is 2001:DB8:0:C030::9A0 .

This looks similar to a practice question we did, but I can't remember if we should keep the "2001" part or not.

I remember something about using "::" to compress consecutive zeros, but I can't recall if we can use it more than once.

I think we need to remove the leading zeros, but I'm not sure if we can shorten it more than that.

This is a good one. I remember learning about IPv6 address compression in the last unit. I'll just need to apply those rules and I should be able to get the right answer.

Wait, what? Compressing IPv6 addresses? I don't think we covered that in class. Let me re-read the question and see if I can figure it out.

Alright, I've got this. First, I'll remove the leading zeros from each group. Then I'll replace the consecutive zeros with a double colon. Easy peasy!

Hmm, I'm a bit unsure about this one. I know we need to compress the address, but I'm not totally clear on the exact rules for doing that. I'll have to think it through carefully.
