AAAA (pronounced "quad-A") records are the IPv6 counterpart to A records. While A records map names to 32-bit IPv4 addresses like 192.0.2.42, AAAA records map names to 128-bit IPv6 addresses like 2001:db8::1.

Why bother adding AAAA records?
- IPv6 visitors connect natively — no carrier-grade NAT, faster handshakes on mobile networks where IPv6 is the default.
- Google ranks IPv6-enabled sites slightly higher (small SEO factor, but real).
- Future-proofing — over 40% of internet traffic is IPv6 in 2026.
If your hosting provider gives you an IPv6 address, add it as an AAAA record alongside the existing A record. Hostinger, AWS, Cloudflare, and most modern hosts provide both automatically.
