This policy setting allows DNS to be used as a prefix information source for non-cellular CLAT. If you enable this policy setting, CLAT will be allowed to discover NAT64 prefixes via DNS. If both NAT64 prefix discovery methods are enabled, the order of precedence is (RA, DNS). If you disable this policy setting, CLAT will not be allowed to discover NAT64 prefixes via DNS. If you do not configure this policy setting, the local host setting is used. A reboot is required for this policy setting to take effect.
