BIND 9.2.4 on RHEL-3 , RHEL-4, and FC3 advisory : preventing IPv6

Some root name servers are now queried first with
IPv6 addresses, which can cause timeouts if IPv6
networking is not initialized .

By default, IPv6 networking is not initialized in
RHEL-3, RHEL-4, and FC3, and 4 second timeouts will
occur when some root name servers are queried first
with their IPv6 addresses.

Initializing IPv6 networking, by adding this line
to /etc/sysconfig/network :
'
NETWORKING_IPV6=yes
'
prevents timeouts occurring for IPv6 queries .
