 +===== DNSSEC =====
 +If DNSSEC validation is not enabled in NIOS, and if NIOS is configured to forward to another DNS server (e.g. NIOS caching/recursive layer) then NIOS sends DNS queries to the caching box with DNSSEC "CD" (Check Disabled) flag bit set to "1", and the caching server, irrespective of the local DNSSEC validation setting,  will not perform any validation locally and provides the response to the "forwarding DNS server", and the same response is sent back to the client. i.e. if you have full DNSSEC validation enabled on the external caching server but the Internal NIOS server does not have DNSSEC enabled then the external caching server will NOT perform DNSSEC validation for that query.
 +
 +If you enable DNSSEC and have Trust Anchors configured on the internal DNS NIOS box, then the NIOS box will do the DNSSEC validation by forwarding the DNS and DNSKEY queries to the external caching layer to get the answers to.
 +
 +If you enabled DNSSEC and have NO Trust Anchors configured, then the internal DNS NIOS box will add CD (Check Disabled) flag bit set to "0" and it will mean that it is telling the external caching server to do the DNSSEC validation on its behalf.

 In the scenario below, the key is to ensure that the first layer has "Add" enabled and that the second and third layer have "Copy" enabled. If we assume that all clients query layer 1, we are good. We include "Add" in the second and third layers to allow for clients querying these layers directly. In the scenario below, the key is to ensure that the first layer has "Add" enabled and that the second and third layer have "Copy" enabled.
