What are DNS Servers for Linux?

DNS servers, short for Domain Name System servers, are public servers that provide a protocol that connects domain names to IP addresses so that web browsers and users are able to navigate to a website using a domain name instead of an IP address. Different free and public DNS servers offer varying degrees of speed and performance. Switching from an ISP's default DNS server to a public DNS server can provide enhanced page load speed and security.
