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 A  and 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.
