What is a DNS Server?
A DNS server is a computer that houses all of the information about websites that are directed through that server. Though there are six major DNS servers, many smaller, DNS servers exist. These public DNS servers are available for anyone to use. With any searching at all, you can find a free DNS server that you can use to host your website. There are a few concepts with which you should familiarize yourself, however.
Public Use DNS Servers
First, when you are looking for a domain name server DNS list, you will need to look for servers that allow public use, whether free or for a fee. A public DNS server is one that allows access to pretty much anybody who needs and wants it. If you purchase your URL from one company and will want to host with another company, then you will need to change the DNS server address on the new computer. Some of the common companies, such as BellSouth DNS servers and Comcast DNS servers, will walk you through everything step-by-step so that it is pretty simple for you.
Dynamic DNS Servers
If you have high-speed internet with a rotating IP address, then you can use free DNS servers, but you need to find a dynamic DNS server. This service will allow your IP address to change but still have your site ping the right location. Otherwise, visitors to your site will get a cannot find server or DNS error every time your IP address changes. A DNS error or server not found error can cause serious problems for your attempts to build up traffic because you will find that people will think that your site is not legitimate if they try to visit once, and the DNS server addresses are not correct.
The Usefulness of DNS Servers
The point is to check DNS servers before you commit to a hosting company or a program. Also remember that with anything, free DNS servers are a great option, but they can provide only so much for you. If you will need more complicated options, including emails, then you will need to search out a paid DNS server for that kind of luxury service. Still the free DNS servers are not all bad. They definitely work for your basic website needs. You just need to know when you outgrow them and be prepared to move on. Of course, by that point, you should be making enough with your site that it will not be a problem.
