Description

This policy enables an override of the IPv6 reachability check. When overridden, the system will always query AAAA records when resolving host names. It applies to all users and interfaces on the device. If you enable this policy, the IPv6 reachability check is overridden. If you disable or don't configure this policy, the IPv6 reachability check won't be overridden. The system only queries AAAA records when it's reachable to a global IPv6 host.
