DNS delegation instances and how-to steps

DNS delegation: A DNS server is responsible for delegating resolution of certain zones to other DNS servers.

Problem: The client resolves data from the uec.com and sina.com two domains through a DNS server.

Scenario: Use delegation to create a private root.

Step 1: Create the uec.com main area on the SERVER01;

Step 2: Create the Sina.com main area on the SERVER02;

Step 3: Create a private root;

Step 4: Create a delegate,

Delegate the uec.com parsing right to SERVER01,

Delegate the Sina.com analytic right to SERVER02;

Step 5: Add the private root to the root list.

Forwarder: The DNS server forwards queries from certain zones to other DNS servers.

Boot file: Boot file, by default, DNS is not booting from the file, but booting from the ad registry.

Ways to modify the boot file: Properties--advanced--load the zone data at startup--from the file.

Zone data file: All record data in this area is stored.

Example: Creating a primary zone by modifying the file's method

Create a Zone data file (BAIDU.COM.DNS)
