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 2
nd
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.
