Qualquer outra coisa que você possa precisar eu fornecerei.
esses IPs são do Google, aposto que eles fazem parte do cluster 8.8.8.8. As consultas que você está vendo - as pessoas estão realmente enviando-as para 8.8.8.8, presumivelmente por causa de um erro de configuração em algum lugar. Você não pode impedir isso de dentro do seu PowerDNS. Você pode ocultar a mensagem desativando log-dns-details (ou seja, log-dns-details=off ).
