When it comes to understanding the concept of the DNS server, all you really need to know as a layperson is that the main function of DNS servers in general is associating a domain name with an IP address so that your web site can be found with the greatest of ease. You also cannot have a web site without the aid of a DNS server, as there would be no place for queries about your web site to be directed. If anyone made the attempt and there was no information available on the DNS sever, the response would be something along the lines of “cannot find server of DNS error”.
There are plenty of DNS servers that can be the perfect location for your domain name server information. You DNS server address may be hosted on a free DNS server or one of the public DNS servers. There is also the Dynamic DNS server, the Bellsouth DNS servers, or the Comcast DNS servers. It is not that hard to determine where your DNS server information happens to reside. You can check DNS servers utilizing the Domain Name Server DNS list and located the various DNS server addresses.

You will not find yourself subject to any problems such as the dreaded "DNS error or server not found” message any more often than anyone who is residing on a private server. In fact, depending on the hardware driving the private server, you may in fact be in much better hands.
