What is a valid IPv6 address record in DNS?
The correct answer is B. AAAA. The AAAA (quad-A) record is the DNS record type used to map a hostname to an IPv6 address. Unlike an A record, which maps a hostname to an IPv4 address, an AAAA record stores a 128-bit IPv6 address, allowing DNS resolution for IPv6-enabled networks.
