What are domain name system servers?
DNS is an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses.
Every time you use a domain name, therefore, a DNS server must translate the name into the corresponding IP address. For example, the domain name www.ukfast.net might translate to 198.105.232.4.
Most Internet services rely on DNS to work. If DNS servers fail or are too slow, websites cannot be located and email delivery stalls.
DNS servers are in fact their own network. The DNS server may communicate with other Internet DNS servers if it doesn't know how to translate a particular domain name.
How does DNS work?
DNS is the basic method which allows a domain name to lead customers to your website as a they attempt to log onto your site. Every time you enter a domain name you use the Internet's DNS Servers to translate the domain name into the IP address to find the web page.
To determine which primary name server contains your domain name records, a local name server contacts the root domain name server.
The root domain name server then returns the IP address of the primary name server responsible for the domain being requested. The primary name server becomes the next machine contacted by the local name server.
The primary name server holds the IP address for the domain name and satisfies the the local name server's request. The local name server can then finally return to the web browser with the IP address.
Using the IP address, the web browser can then contact your company web server and retrieve your web pages.
