No actually, they are saying the the Root DNS server's found to authorative Name Servers for the a-record access.pepsi.com.<br />
<br />
In this case the authorative servers: ns-1.pepsi.com and ns-2.pepsi.com are both authorative for the domain and each one has an a record for the host address access.pepsi.com.<br />

First, thank you.<br />
Just to confirm,<br />
<br />
<br />
The public Root servers see that NS1-pepsi.com and NS-2-Pepsi.com are authoratative for pepsi.com. Both those name servers have an A-record for access.pepsi.com.<br />
<br />
In an example like this, how does the Root server know which Name server to send the request to? Is it load balancing or will it send the DNS request to both NS1 and NS2?<br />

Hi experts,<br />
<br />
I'm not a DNS experts but I am studying a concept of load balancing DNS.<br />
<br />
If someone said:<br />
<br />
&quot;The Root DNS servers provide the nameservers for Access.pepsi.com as the NetScalers ADNS servers namely: ns-1.pepsi.com (200.200.200.150) or ns-2.pepsi.com (100.100.100.150).&quot;<br />
<br />
<br />
Are they saying that the root DNS server are authoratative for Access.Pepsi.com?<br />
And that the Root DNS has an A-record for access.pepsi.com that point to two IPs 200.200.200.150 and 100.100.100.150?<br />

DNS root servers

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
