[ale] DIG failing due to ipv6?

 Ok, this is un-related to my previous IPv6 question, as this is for work
and we do not have IPv6 rolled out. We are trying to look up a signle sign
on page hosted in azure and it looks like dns is failing because my bind9
is geting an IPv6 address for the dns server but can't get to it to query
the real DNS name.



I thought I disabled IPv6 resolution and forced IPv4 only but it doesn't
seem to be working. Anyone have any ideas?

Anyone have any ideas how to resolve this?
