Public Domain Name System is a public service provided by numerous companies. This service assigns Uniform Resource Locators for websites. Each system or server connected to the Internet is provided with an IP address. An IP address is made up of a series of numbers with periods in between them. The format for an IP address is: 000.000.0.0.
A user can publish a website on the Internet with just an IP address. Users can type in an IP address on a Web browsers’ address bar and it will direct them to the home page of the server. The numbers may be a bit hard to remember if the user wants to generate large traffic for their website.
DNS is used to assign websites to IP addresses. When the user types a URL on the address bar, the system will refer to the DNS to check which IP address it corresponds to. The Web browser will then be directed to the IP address of the website.
How Does Public DNS Work?
If you’re talking about a published primary DNS, there are five steps to perform. However, if you have a registered domain, there are only three steps. Moreover, if you only want to have an MX record, you can skip the last step.
You will first have to find an unused domain name. This is because you won’t be able to register it if someone else is using it. When you are able to register it, you can create a primary DNS account. To create a DNS account, make sure that you choose the right service provider. Delegate the domain and re-delegate the in-addr domain.
The DNS service will usually provide service for anyone that requests it, as long as they have the administrative authority over the area. The service provider depends on the zone you are in. However, if you are in a company capable of providing its own DNS service, you should do so instead of relying on outside or public DNS. This way, you are assured of controlled efficiency.
How to Delegate the Domain
To delegate the domain, you have to pick the service provider that suits your needs. The company will supply you with instructions as to how to create and delegate your domain after you have created an account with them. There are always providers that offer free services.
What are the Restrictions?
Service providers often have restrictions on the usage of the service. These restrictions vary from one company to another. Usually, registrants are required to claim ownership of the zones they want to register. Also, they should be using resources they are given authority to use. These restrictions are always bound by legal issues.
To start with secondary DNS, authorize your service provider to perform zone transfers from your primary name server.
After that, create a secondary domain account and have it registered. Now, you can delegate the domain and wait for confirmation before using it.
