What is DNS Record?

DNS means Domain Name Service. First and foremost we should be aware of the terms Internet names and Internet address. Internet names are those names used to mention the hosts on the internet for example: http://www.globaliway.com. Here globaliway is referred to as internet names used in the browser. Internet address are the address normally the numbers which are being used to move traffic across the internet for example 74.53.110.114. Where name stands for internet names and numbers stands for internet address. DNS service  translates its service between internet names and internet address.  Usually this service is provided by the hosting company  or given by the registrar where the domain is registered.

What are DNS Records?
DNS records or Zone files are used for mapping URLs to an IPs. These records are located in the DNS server. It connects your website with the outside world. When the URL is typed on the browser it is being forwarded to your DNS servers and then get pointed to webservers.  These webservers serve the website mentioned in the URL or the Email server which handles the incoming email.

Types of DNS Records:
