DNS Server is used to resolve IP address assigned to Domain name. When you type a website name or domain name into an app—like your browser, your computer sends a request to ISPs default DNS server to get resolved IP address (assigned to that domain name). When your computer gets the IP address, it sends another request to the IP address to get the data required to render that webpage, that’s how the internet works.
So when you search a lot of websites, your browser has to resolve all the domain name to IP addresses, and this takes time. Sometimes your internet service providers default DNS server might slow down the process a little bit. So you can use alternative free and public DNS server to speed up IP resolving, this will make your browsing faster.
Please know that it will not increase your internet bandwidth but it will help quickly resolve IP address of a particular domain name. So your computer can send request to render the web page faster.
