Configuring DNS servers, zones, and resource records
In Chapter 3, Managing Windows Active Directory, in the Installing Active Directory with DNS recipe, you installed a DNS server as part of the installation of AD. This enabled DC1
to be an initial DNS server that provided a home for the various DNS records that were created by AD for the Reskit.Org
domain. Adding a DHCP scope with DHCP options that specify 10.10.10.10
(the IP address of DC1.Reskit.Org
) means that DHCP clients use DC1
as their DNS server (and register their IP addresses with DC1
).
After you perform these two recipes, DHCP clients receive IP address configuration, which includes a DNS server. Thus, DHCP clients can easily resolve IP address for each other and for the domain forest infrastructure (DNS resolution provides AD clients with IP address details for the domain controller and global catalog servers).
The DC installation process, combined with DNS auto registration, means that basic DNS operations just work for DHCP...
