AAAA रिकॉर्ड
Maps a domain name to an IPv6 address.
AAAA रिकॉर्ड क्या है?
The AAAA record (read "quad A") points a hostname at an IPv6 address. It mirrors the A record but uses the 128-bit IPv6 address space. Modern services should publish both A and AAAA records.

सामान्य उपयोग
- ▸Dual-stack web servers reachable over both IPv4 and IPv6.
- ▸Mobile carrier networks that are IPv6-only — clients need AAAA to reach you.
- ▸Future-proofing apex records before IPv4 reachability is reduced.
- ▸CDN edge nodes that announce IPv6 directly.
सामान्य भूलें
Happy Eyeballs (RFC 8305) lets browsers try v6 then fall back to v4. A broken AAAA (host listed but not reachable) can introduce noticeable load delay before the v4 fallback kicks in — always verify reachability after publishing.
