Active Directory-integrated zones provide enhanced security for DNS updates and zone replication traffic in several ways all DNS servers hosting Active Directory-integrated zones must be registered in AD AD replication traffic is encrypted and you can use access control lists ACLs to restrict the hosts that are allowed to update RRs using DDNS secure dynamic updates . Stealth servers When you register the name servers that are authoritative for your Internet domain namespace you must supply at least one or two name servers that are authoritative for the zone so that authority can be delegated from the parent domain .com .net and so on to your servers. It is possible however for these servers to be secondary or slave servers to a primary master server that is not listed in the registered NS records for the zone listed by the registrar as being authoritative for your domain. Usually the primary master server is located behind a firewall and access to the primary server itself and zone transfers to the secondary servers are tightly controlled by access rules on the firewall. Caching name servers A caching name server performs queries on behalf of DNS but the server itself is not authoritative for any zones. When you first set up a Windows DNS server with the root hints file it is a caching name server that can resolve queries for Internet hosts using information it possesses about the name servers that are authoritative for the root zone. After time the caching name server builds up a list of commonly queried names in its cache which is subsequently used to answer queries on behalf of clients. Forwarding servers A forwarding server is a kind of caching name server that sends queries to a predetermined list of name servers known as forwarders which can perform recursive queries on its behalf. The forwarding server will send its query to each forwarder
