How to disable IPv4 and enable only IPv6 on arm Linux target?

I am testing bind9 dns server for AAAA records. I would like to disable IPv4 to stop dns requests going to my default ipv4 dns server.

In the resolv.conf i have added

    domain mydomain.com
    nameserver xxxx:xxxx:xxxx:xxxx:xxxx::xxxx
    search mydomain.com

When I try to call

    getaddrinfo("mydomain.com",NULL,&hints,&res);

to resolve the domain name to IPv6 address , I see error message "No Route to Host".

The same program can resolve to IPv6 address when i run on the Ubuntu PC.

I have tried to test

    nslookup mydomain.com
    server:    10.1.xx.xx
    address 1: 10.1.xx.xx    dnsserver.com
    nslookup: can't resolve 'mydomain.com'

The nslookup command works correctly on Linux PC.

Is there any thing additional I need to do in the /etc/network. or else where?

Edit:

The issue is resolved with changes in the bind9 reverse zone configuration file.
