Question

While reviewing logs on a firewall, you see several requests for the AAAA record of . What is the purpose of this request?

Answer 1

AAAA record requests observed in firewall logs suggest that network devices are resolving IPv6 addresses for domain names. An AAAA record is a DNS record that maps a hostname to a 128-bit IPv6 address, essential for networks supporting IPv6.

Step-by-step explanation:

Reviewing logs on a firewall and noticing several requests for the AAAA record indicate that devices on your network are trying to resolve IPv6 addresses for domain names. An AAAA record is a type of DNS record that maps a hostname to a 128-bit IPv6 address, which is the successor to the older 32-bit IPv4 address system. The purpose of these requests is similar to the more common A record, but instead of returning an IPv4 address, it returns an IPv6 address, which is crucial for devices that are communicating over a network that supports the IPv6 protocol.
