Thank you Ben,"With no forward {} the path for blah.bar.foo.com directed at server A will be A > C > B"Do you see any reason why I would use this non optimal path ? In your example, how would C contact B, there would be a zone forward ?Regards

With no forward {} the path for blah.bar.foo.com directed at server A will be A > C > BWith forward {} the global forward will be short circuited for foo.com and below resulting in a path of A > B On May 12, 2017 11:56 AM, "Mik J" <mikyde...@yahoo.fr> wrote: Thank you Ben for your answer My server uses a global forwarding I don't understand what you wrote"If it is master for a foo.com and also has global forwarding it will use the global forward for any delegated child domains under foo.com unless they are also loaded locally." If my DNS is autoritative, why would I use a forwarding ? For my sub domains I use delegationssub.mydomain.com NS ns.sub.mydomain.comns.sub.mydomain.com A 1.1.1.1 What's the difference between the global forward for delegated child domains and the delegation I do ? Thank you Le Vendredi 12 mai 2017 15h34, Ben Croswell <ben.crosw...@gmail.com> a écrit : This would only change behavior if the server has global forwarding. If it is master for a foo.com and also has global forwarding it will use the global forward for any delegated child domains under foo.com unless they are also loaded locally. The forward{} turns off global forwarding for that branch of the tree.

In other terms why would I wantzone "mydomain.com" { type master; file "zones/master/com/mydomain.com "; allow-update { acl; }; }; Instead of (forwarders {};)zone "mydomain.com" { type master; file "zones/master/com/mydomain.com "; allow-update { acl; }; forwarders {};}; Why would I want to forward requests if I'm autoritative for the zone ? Thank you for those who can hightligh this point. ______________________________ _________________ Please visit https://lists.isc.org/mailman/ listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/ listinfo/bind-users
