A server's name should resolve to its IPv6 address. Which DNS record stores that address?
Select an answer to reveal the explanation.
Short Explanation
The name needs a tag for the longer IPv6 number, not the older IPv4 tag. You publish an AAAA record. An IPv4 address record, a mail record, and a text record do not store that IPv6 address.
Full Explanation
An AAAA record maps a name to an IPv6 address. The server's name should resolve to its IPv6 address, so the AAAA record is the one to publish. An A record maps a name to an IPv4 address. It does not store the IPv6 address. An MX record names a mail exchanger. It is not the host's IPv6 address record. A TXT record holds text such as a mail policy. It is not the address record for IPv6. Exam caveat: the host can have both an A record and an AAAA record. Clients that ask for IPv6 need the AAAA. Leaving only the A record does not answer them. Operational check: query the name for AAAA and confirm the server's IPv6 address is returned. Query the name for the IPv6 record and confirm the address that comes back. Record the result on the ticket before you close the call. Add the IPv4 record only if clients still need it. Do not pretend it is the IPv6 record.
