I have Ubuntu server with both IPv6 and IPv4. IPV6 queries made before IPV4 and they where wasting resources, and also there is still no route to some network. After read from some web resources, I got that it's the standard to prioritize IPv6 over IPv4.
I did changed my /etc/gai.conf (gai stands for getaddrinfo, the standard system call for resolving host names). For sites which prefer IPv4 connections change the last line to:
precedence ::ffff:0:0/96 100
And then, my Ubuntu server query A records (IPv4) before AAAA records (IPv6) when access domains.
