Question

Which one of the following DNS record types holds the name-to-address mapping for IPv6 addresses?

A) A
B) AAAA
C) CNAME
D) PTR

Answer 1

The correct DNS record type for mapping IPv6 addresses is the AAAA record.

Step-by-step explanation:

The correct DNS record type that holds the name-to-address mapping for IPv6 addresses is the AAAA record.

The AAAA record is specifically designed to map hostnames to IPv6 addresses, while the A record is used for IPv4 addresses.

For example, if you have a hostname like 'example.com' and an associated IPv6 address '2001:0db8:85a3:0000:0000:8a2e:0370:7334', you would use an AAAA record to establish the mapping between them.
