What is AAAA Records?
AAAA records are DNS records that map a domain name to an IPv6 address. Cloudflare explains that AAAA records do the same job as A records, except they store IPv6 addresses instead of IPv4 addresses. :contentReference[oaicite:7]{index=7}
What they are
A AAAA record is the DNS record type used for IPv6 addressing. It links a domain name to an IPv6 address so systems can find the correct destination. :contentReference[oaicite:8]{index=8}
How they work
When a resolver checks DNS for a domain that uses IPv6, the AAAA record provides the IPv6 address needed to connect. It works like an A record, but for the IPv6 protocol family. :contentReference[oaicite:9]{index=9}
Why they matter in real life
AAAA records matter because IPv6 support is part of modern internet compatibility and network growth. Services that support IPv6 often publish AAAA records alongside or instead of A records. :contentReference[oaicite:10]{index=10}
Common misconceptions
A common misconception is that AAAA records replace A records everywhere. In practice, many services still use both, depending on whether they support IPv4, IPv6, or both. :contentReference[oaicite:11]{index=11}
