IT Technology: Will Domain Name System (DNS) Affect Browsing Experience / Internet Slow?

Yes. DNS will definitely affect your browsing experience or cause the Internet slow.

The Domain Name System (DNS) is an hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates easily memorized domain names to the numerical IP addresses needed for the purpose of locating computer services and devices worldwide. By providing a worldwide, distributed keyword-based redirection service, the Domain Name System is an essential component of the functionality of the Internet.

Improper DNS selection will cause packet drop and high latency. Thus, this will affect your browsing experience and Internet slow. 

In Malaysia, if you are using TM service, you may want to use the following DNS so that you can browse the Internet smoothly.
