What A and AAAA labels mean in the logs?
Those are the type of DNS queries performed by your device. The
A type is used to resolve IPv4 address and
AAAA for IPv6.
Typically, you either see
A alone or duplicated queries for
AAAA . Those duplications are expected, it means your network is dual stack (supports both IPv4 and IPv6). Note that we do *not* count two queries against the free plan limit for dual stack networks.
