IPv6 Root AAAA Record

What This Check Does

The IPv6 Root AAAA Record check verifies that an AAAA record exists for your domain apex (e.g., example.com). An AAAA record maps your domain to an IPv6 address, enabling users on IPv6 networks to access your website and services directly.

DNS Spy queries the AAAA record for your domain's root and verifies that at least one valid IPv6 address is returned.

Why It Matters

IPv6 is the future of internet addressing. IPv4 address exhaustion is a reality, and many networks — particularly mobile carriers and ISPs in Asia, Europe, and developing regions — are increasingly IPv6-only. Without an AAAA record at your domain apex, users on these networks may be unable to reach your website.

Adding an AAAA record to your domain apex signals that your infrastructure is modern and prepared for the ongoing IPv6 transition. While this check is lower criticality since most networks still support IPv4 fallback, it represents an important step toward full IPv6 readiness.

Good vs. Bad Configuration

Bad Configuration

example.com has only an A record (198.51.100.1) with no AAAA record. Users on IPv6-only networks cannot directly connect to your domain.

Good Configuration

example.com has both an A record (198.51.100.1) and an AAAA record (2001:db8::1). The domain is accessible over both IPv4 and IPv6.

How DNS Spy Monitors This

DNS Spy checks for the presence of AAAA records at your domain apex during every monitoring cycle. If no AAAA record is found, the check is flagged. DNS Spy also tracks changes to your AAAA records over time, notifying you if an IPv6 address is accidentally removed from your configuration.
