If you’ve only configured A records, you may still see a large number of AAAA queries in your DNS logs. This is expected behavior.
Why this happens
The global shortage of IPv4 addresses has driven a large-scale migration to IPv6 networks. Most global infrastructure currently runs IPv4 or a dual stack of IPv4 and IPv6, but the migration to IPv6 is ongoing.
As a result, many clients, browsers, and applications on IPv6-enabled networks now prioritize IPv6 lookups. When resolving a domain, they first issue an AAAA query to look for an IPv6 address. If no AAAA record is configured, they fall back to an A query for an IPv4 address.
Bunny DNS logs these AAAA queries with an empty answer. The queries are harmless.
Recommendation
Configure both A and AAAA records for your domain when possible. This avoids the fallback round-trip and improves resolution time, which can improve overall performance for your website or application.
