[Unbound-users] Unbound and Bind Views

Hayward, Bruce
Mon Oct 25 15:18:20 CEST 2010


On specific resolvers we use bind views to direct those who come from an IP in a specific CIDR to use a specific zone.  We have two cases of these views.

We also use views to isolate those that should only use internal zones versus those that should not use internal zones (external customers)

Those that do not come from an IP in a specific CIDR use a global zone.

"Views" were introduced in Bind 9.

Hey Bruce,

I think that it's pretty well documented in the mail you sent a
link...  you setup two unbound instances and mangle the traffic from
set of ip addresses using standard firewall/nat features your
operating system has.

Anyway maybe if you can explain what you are trying to accomplish then
we can propose alternative without views.
