    <p>A nameserver is a program that maintains a list of your domain names and their corresponding IP addresses, allowing visitors to find the domains hosted on your server. It is a vital component of the networking setups of most servers. However, servers using a remote nameserver do not need to configure their own.</p>
    <p>Here you can select the nameserver you wish to use, if any.</p>
