Migration to application partitions
Application partitions enable certain data to be replicated along partition lines. Specifically, application partitions assist with control of the replication’s scope—for instance, to enable certain DNS zones to be replicated.
An application partition is created with the dnscmd command-line tool:
dnscmd <ServerName> /CreateDirectoryPartition <Fully Qualified Domain Name>
After the partition is created, servers are enlisted with this command:
dnscmd <ServerName> /EnlistDirectoryPartition <Fully Qualified Domain Name>
After the directory partition is created, you can change zone replication in the Properties sheet for the given zone. On the General tab of the zone’s Properties sheet, you change the replication configuration by clicking Change. Figure 2-10 shows the General tab.

When you click Change, the Change Zone Replication Scope dialog box appears, as in Figure 2-11.

IPv6
Windows Server 2012 supports IPv6 DNS hosting. Address records are known as AAAA in IPv6 rather than the A record for IPv6 DNS hosts. Designing IPv6 DNS typically means a coexistence strategy of some nature whereby both IPv4 and IPv6 DNS is supported on a network.

Windows Internet Name Service (WINS) doesn’t support IPv6, so keep this limitation in mind when planning an IPv6 deployment. You can use an ISATAP router to provide translation services for WINS.
