Every connection to the internet relies on the Domain Name System, which is supplied by your network provider. These default servers don’t always prioritize speed or security. If it takes a long time to load a website, you might be better off with a fast DNS service from a third-party.

What are DNS servers?

DNS stands for Domain Name System. Think of it as a phonebook or a contact list, containing names and corresponding numbers. But in this case, the numbers are Internet Protocol addresses and the names are website addresses. Whenever you enter a domain name into a search engine, the DNS server lets you look up the IP address for the site.
