DNS servers help to fetch the correct IP address of the URLs requested from a client computer. All browsers like Safari, Chrome or Firefox running on a client computer by default use the DNS server settings of the Internet Service Provider (ISP). Sometimes it is necessary to change the default DNS servers in order to ensure unrestricted, safe and fast surfing experience. This also will help to resolve IP related problems like resolving host issue in Google Chrome browser and helps the sites load faster.
