Question 1

What is a DNS AAAA record

Accepted Answer

An AAAA record maps a domain to an IPv6 address. It is the IPv6 counterpart to an A record, which maps to IPv4.

Question 2

Why do I see no AAAA record

Accepted Answer

Many domains are still IPv4 only. If the A lookup returns results and AAAA does not, the host likely does not publish IPv6.

Question 3

How do brackets work with IPv6

Accepted Answer

Brackets are used only when an IPv6 literal appears in a URL host, for example https://[2001:db8::1]/. They are not needed in path parameters.
