Delegation (private root)

Experimental purpose: The client resolves data from a uec.com,sina.com,baidu.com three domain through a DNS server.

1. Create a uec.com primary zone on the LZ server and create a record of adhesion a

2. Create a sina.com primary zone on the LZ1 server and create a record of adhesion a

3. Create a private root on the LZ2 server

650) this.width=650; "title=" image "style=" border-left-0px; border-right-width:0px; Background-image:none; border-bottom-width:0px; padding-top:0px; padding-left:0px; margin:0px; padding-right:0px; border-top-width:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M01/5C/3C/wKiom1Uc5T_ A3tepaabfsuktcig201.jpg "width=" 244 "height="/>

4. Create a delegate

(1) Delegate The Uec.com's resolution to the LZ server

(3) on the LZ2 root domain server, the resolution of the uec.com is delegated to the LZ server

650) this.width=650; "title=" image "style=" border-left-0px; border-right-width:0px; Background-image:none; border-bottom-width:0px; padding-top:0px; padding-left:0px; margin:0px; padding-right:0px; border-top-width:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M02/5C/3C/wKiom1Uc5T_ Sdynxaabn72e7x3k655.jpg "width=" 244 "height=" 204 "/>

(4) on the LZ2 root domain server, delegate the resolution of Sina.com to the LZ1 server

650) this.width=650; "title=" image "style=" border-left-0px; border-right-width:0px; Background-image:none; border-bottom-width:0px; padding-top:0px; padding-left:0px; margin:0px; padding-right:0px; border-top-width:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M00/5C/3C/ Wkiom1uc5upd7w8aaabqpmxgn7a570.jpg "width=" 244 "height=" 205 "/>

5. Test: Can DNS point to 192.168.1.103 (the address of the LZ2 server) parse out all the data?

(1) on the LZ server

650) this.width=650; "title=" image "style=" border-left-0px; border-right-width:0px; Background-image:none; border-bottom-width:0px; padding-top:0px; padding-left:0px; margin:0px; padding-right:0px; border-top-width:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M00/5C/37/ Wkiol1uc5oorjbjqaabx4y0z-co065.jpg "width=" 244 "height=" 207 "/>

(2) The same operation on the LZ1 server

6. Add a private root to the root list

On the LZ server

Property----Root Hints-----add------LZ2 192.168.1.103

650) this.width=650; "title=" image "style=" border-left-0px; border-right-width:0px; Background-image:none; border-bottom-width:0px; padding-top:0px; padding-left:0px; margin:0px; padding-right:0px; border-top-width:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M00/5C/37/ Wkiol1uc5opx6lf3aacgwdnsxvu401.jpg "width=" 205 "height=" 244 "/>

On the LZ1 server

650) this.width=650; "title=" image "style=" border-left-0px; border-right-width:0px; Background-image:none; border-bottom-width:0px; padding-top:0px; padding-left:0px; margin:0px; padding-right:0px; border-top-width:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M01/5C/37/ Wkiol1uc5opikwpnaacfusud6uy063.jpg "width=" 207 "height=" 244 "/>

Test: The LZ server DNS point to 192.168.1.101, to see if all the data can be resolved?

650) this.width=650; "title=" image "style=" border-left-0px; border-right-width:0px; Background-image:none; border-bottom-width:0px; padding-top:0px; padding-left:0px; margin:0px; padding-right:0px; border-top-width:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M01/5C/3C/ Wkiom1uc5utg8bcdaabwigzs630896.jpg "width=" 244 "height=" 222 "/>

The result is a successful resolution of all data, the end of the experiment
