There are a number of advantages associated with using a domain nameserver in your organization. First, the use of a nameserver reduces your IT overhead by providing a means for all employee computers to connect to one single server. Second, it allows you to create more addresses for employees. Third, having a nameserver is especially useful if your company has more than a few locations or sites. By delegating the responsibility for DNS zones to the nameserver, your network administrators can free their time to handle other duties.
For many small businesses and home-based operations, there is a lack of available IP addresses for DNS servers. If you are stuck running a single dns server and trying to provide multiple zones for customers and employees, it is nearly impossible to get everything from your computer to a point where all of them have access to the information you want them to have. You will need to rent or lease an IP address from a web hosting provider and then configure all of your computer's networking hardware and software so that each machine has a unique IP address that corresponds to the DNS zone it is intended to serve. One way to make sure that you get this done is to purchase a recursor, which is a special program designed to mask the actual IP address of your domain name and instead provide a numerical representation of it.
There are a number of nameservers available on the web today and Nameserver 2021 is among the most popular. The advantages of using a nameserver to protect your domains include the following. It will allow you to create multiple copies of any domain for backup purposes. It will also prevent some types of hacking that can wipe out a portion of a domain or even completely take it down. Finally, a nameserver will provide the means for a given website to have its own mail server so that emails can be sent from that domain and all email addresses associated with that domain will have the proper authorization.
