There are millions of websites live and operational on the internet. They are hosted and managed by web servers that are located all over the world. To find a website and where it's being hosted requires a directory, without which it would be virtually impossible to find websites. DNS stands for Domain Name System which is the largest digital database for the internet in the world. This database contains information about every website in the world. Every website and every machine that comes on the internet has an IP address which is a digital address. The domain name of a website is stored along with its IP address in this database. The data files that tell a web server how to respond to a request by a search browser are known as DNS records.
