What is a DNS server? DNS is an acronym that refers to Domain Name Server. It is like a telephone directory. To put a directory entry in a database, a DNS server pulls that entry from it via a request. It can be a private server or a public DNS servers. Public servers WILL NOT accept users from outside their network. Therefore when a DNS server receives a request to add another entry to the database, it must do so. The most common features are the nameserver, root DNS zones, and domain not specified zone, or all zone with one name. Every domain name starts with a name server, usually nothing, and runs the entire system.
The name server is the front-order address on the Internet. Without this entry, the request can’t be recognized. Certain top-level domains run systems called root servers that make them much more important than the local top-level domain.
Many search engines know the addresses of the root servers and direct requests accordingly. Furthermore, many search engines have Adam fairings that give them the directory or even email addresses of the highest authority and most trusted DNS servers. Therefore when your domain name is selected through one of these computers, you will be able to easily find a supplier if anything goes wrong. However, not all of them are adequate. There are many DNS servers that have no information on the IP addresses of their target/programs.
Some webmasters opt to use a separate IP address of a different company for their server. This allows them access to a larger number of domain names from a less diverse pool of servers.
Select a Dns Server that is a Friend
If your server will not accept requests from outside the network it will not be reliable. If there are hundreds of DNS servers the only servers that get higher priority are those that direct to your server or are in your exact geographic location.
If you are looking for a server that is local to your site make sure that it is local to the program that you wish to run.
Beware of DNS Servers that Look Like Your Own Sub-Domain
This happens when a server looks the same as other domains that you have registered with the same host. This may cause your site to lose traffic from your “real” domain if the search engines mistakenly think that it is yourself – and you are the only one listed.
Look for a constant IP address and use that to make sure each time you start a new site will be at the top of the server queue rather than the local server.
Server Timeliness
It is important to note that DNS servers may not always be the fastest because of the surge in number of new connections because of a DNS refresh or the lead time needed to pass the change.
Most servers that are actually your domain will load in the same time. It may take a few seconds to load the initial information for the domain. Servers are very fast when first starting up and after a server has been up for a few hours.
How often is the DNS server updated?
This is easy. Once a DNS provider renews with you the IP address you will find out that the program that is listed in the domain name server once update. This will let you know when to get on in the name server to update – but only to change the DNS settings to the newer settings.
You will not find this with free-for-all DNS servers. There is no fixing or worksarounds the the provider. Make sure that you get a DNS provider that works in your best interest.
