Authorities DNS is just a fancy term for the official IP address keeper/provider of particular Domain (or Internet)
name, such as www.example.com is analogous to a telephone book where a person’s name is associated
with his telephone number. Wikipedia, the free encyclopedia has a good general discussion of DNS:
This IN-BOUND ROUTER DNS server contains the names and Internet addresses of servers that you wish to
host. In order for all DNS requests of your domain names to be ultimately routed to your IN-BOUND
ROUTER, it has to be setup at the registrar of your Internet name. In general, logon to your registrar site, and
manage your domain name. For example, www.example.com is located at a WEB hosting company, and the
original Domain server was registered in listed order:
NS0.DNSMADEEASY.COM NS1.DNSMADEEASY.COM NS2.DNSMADEEASY.COM
NS3.DNSMADEEASY.COM NS4.DNSMADEEASY.COM
We need to change www.example.com to be hosted by IN-BOUND ROUTER; so we follow the registrar’s
instructions and delete: NS2, NS3, and NS4, and assign Domain server:
Name
IP address
NS0.EXAMPLE.COM WAN1
NS1.EXAMPLE.COM WAN2
The name is arbitrary; the most important are about the IP addresses. It is absolutely necessary for WAN1
to be a static address, and for redundant, fault-tolerant accesses, WAN2 should also be a static address. It
would take approximately 24 – 48 hours for this change to take effect throughout the Internet. Below is the
actual display of godaddy for Name Servers:
All registrars have the same basic name server
facility. For www.example.com, we use
godaddy.com, and the process is: Login Manage
domain Set Name Servers. We enter WAN1 and
WAN2 for Custom Name Servers.
