Disabling IPv6 lookups in bind
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'
