DNS > How to Create Internet N Internal DNS Domain Name

An Internet DNS domain name is composed of a top-level domain name (such as .com, .org, or .edu) and a unique subdomain name chosen by the domain owner.


When you have selected your Internet DNS domain, conduct a preliminary search of the Internet to confirm that the DNS domain name that you selected is not already registered to another organization. If you do not find that your domain name is already registered to another organization, contact your Internet service provider (ISP) to confirm that the domain name is available and to help you register your domain name. Your ISP will probably set up a DNS server on its own network to host the DNS zone for your domain name, or it might help you set up a DNS server on your network for this purpose.


How to Creating Internal DNS Domain Names?


For your internal domains, create names relative to your registered Internet DNS domain name.

If you are deploying DNS in a private network and do not plan to create an external namespace, you should nevertheless consider registering the DNS domain name that you create for your internal domain. If you do not register the name and later attempt to use it on the Internet, or connect to a network that is connected to the Internet, you might find that the name is unavailable.
