AAAA Record — AAAA Record (IPv6 Address / Quad-A)
Maps a domain name to a 128-bit IPv6 address (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

Ensure your web server and firewall actually accept and route IPv6 traffic before adding an AAAA record, otherwise IPv6 visitors may experience connection timeouts.
Primary Use Cases:
- •Enabling modern IPv6 traffic for Cloudflare, AWS CloudFront, or Vercel edge networks
- •Complying with Apple App Store IPv6-only network requirements
Common Configuration Mistake
Formatting IPv6 addresses with port numbers or surrounding brackets in DNS zone files.
Always verify records using authoritative queries (`dig @1.1.1.1 $AAAA example.com`) to bypass local ISP caching when debugging propagation delays.
Frequently Asked Questions
DNS AAAA Record Questions & Answers
Common questions regarding DNS propagation, TTL settings, and zone file syntax.
The AAAA (Quad-A) record operates identically to an A record, but handles modern 128-bit IPv6 addresses. Dual-stack servers publish both A and AAAA records, allowing IPv6-capable clients to connect with lower routing latency.
