4.1.7.3. DNS Server Setup

1.Click on the DNS Servers link under Time Sync, and the DNS Servers Settings screen will appear displaying the four (4) default public DNS servers (see Figure 4-14).

2.Enter Domain Name (default = local as Zero Configuration uses dot local).

3.To define your own DNS Server, highlight the desired IP Address and enter

your IP address (max. = 46 characters). It is recommended to use the DNS Server 1 for your first DNS Server IP Address, using DNS Server 2 for your 2nd DNS Server IP Address, and so forth. This is because the clock will use the DNS Servers in appearance order. Therefore, it is recommended to leave the servers you are not using blank.

NOTE: The Domain Name System (DNS) is a hierarchical naming system for computers, services, or any resource participating on the Internet. It associates information with domain names assigned to such participants. Most importantly, it translates humanly meaningful domain names to the numerical (binary) identifiers associated with networking equipment for the purpose of locating and addressing these devices world-wide.

An often used analogy to explain the Domain Name System is that it serves as the "phone book" for the Internet by translating human-friendly computer hostnames into IP addresses. For example, www.blackbox.com translates to 38.107.149.196.

4. Click the button to save your DNS Server information.

Only define the DNS Servers you are using.
