CNAME seems like it could be relevant, but I believe that's for aliases, not direct IP addresses.

I feel like I've seen a similar question before, and I think we had to update the A record for IPv4 changes.

I'm not entirely sure, but I remember something about AAAA records being for IPv6. So, it can't be that one.

I think the answer might be D) A, since that's the record for IPv4 addresses, right?
