The tool that translates domain names into IP (Internet Protocol) addresses is the domain name server (DNS). The IP addresses that the DNS translates domains into are numeric.
These numeric IP addresses are what are read by computers. Computers will not be able to read the domain name address that people use in order to more easily identify a particular website or web page. IP addressees are usually provided by a Domain Name Server (DNS) who is located in close proximity to someone’s ISP (Internet service provider). For instance, quite a few people have chosen AOL or Netzero as their ISP (company who provides internet service), and these DNS addresses are provided with close range of these companies.

Domain Name Server (Dns) Issues
Sometimes the DNS cache needs to be cleared. This process is also sometimes is referred to as “NS cache flushing” which is the practice of removing unwanted information from a certain temporary file folder (i.e. internet search history). Sometimes this cache cleaning is provided for free, and provides a way for DNS cache clearing to be performed with one click. Whenever you are attempting to use freeware, however, beware of possible spy ware and viruses that could harm your computer.

You may want to try to find a trusted paid service that you know will not “spy” on you or harm your computer. This service may be provided through your ISP or your web hosting company. If you cannot clear your DNS cache you may need to either consult your web host or internet service provider. There could be a problem with the DNS address you were assigned. Another issue that involves the use of a DNS is that sometimes a domain name server (DNS) address is not valid. In order to know for sure if it is you may need to do a DNS query. If you are having any additional problems it may be necessary for you to consult your web host, Internet Service Provider, or other tech professional for more information.

Additional Domain Name Server (Dns) Info
In order to determine if a Domain Name Server address is valid you may want to perform a DNS lookup. This is done by way of a simple search, done either by IP address or domain name. You can also complete a DNS or reverse DNS lookup to determine if a person or organization is included on a spam list. This is very useful when planning a course of promotional action. It is important for you to register any domain name that you use. It will be easier to have it supported by a web host if you do. Quite a few inexpensive web hosting services are available to you if you are in search of one.
