Just disabling bind to listen on IPv6 addresses does not prevents it from querying for IPv6 addresses to remote hosts. To ensure that IPv6 is completely disabled use:
- Edit /etc/sysconfig/named and set
- OPTIONS="-4"
- Edit '/etc/named.conf' and set
- filter-aaaa-on-v4 yes;
- Also optionally comment 'listen-on-v6 port 53 { ::1; };'
- Finally use 'service named restart'
