Why Change DNS Servers

Changing your ISP’s default DNS servers can grant you:

  • Better browsing speed (by resolving domain names faster)
  • More reliable service (by preventing fishing or malware)
  • Avoid censorship (from governments) and unlock websites, such as AlfaFile.net

If you are using your ISP’s default DNS servers you really should consider changing your DNS provider for a more reliable and secure option. Follow this article to know what is DNS and how to change it. In the end, if you're not happy you can reset it back to the default DNS servers very easy.

What is DNS Servers

DNS stands for Domain Name System and is a protocol, or language, that computers use when talking to each other. Every device on the public Internet has an IP address and DNS is like a language that converts an IP address like, into the appropriate domain name, like audiok.info for instance. Like this you don't have to memorize a series of numbers which is more difficult to the average human, instead you only have to know a name.

DSN servers are like a dictionary that converts and delivers information by making the right connection, and who controls the DNS servers can redirect you to the right domain or not. In some cases they can even prevent you from access free knowledge and information, like how some Governments are doing by forcing some ISP's providers to block certain websites.

Public DNS Servers

Your home router is likely set by default to use your ISP’s DNS servers, which may or may not be very reliable. There are a number of third-party DNS servers, however, we strongly recommend OpenDNS or Google Public DNS, preferably opting for the later.

Open DNS offers a neat service but we found some extra connections (mainly due to their more advance customisation options and family packages) and their servers are slower.

Google is one of the most reliable and powerful companies in the world and Google Public DNS servers are faster and very reliable, we advise opting for Google Public DNS.

Every major DNS service has at least primary and secondary servers to ensure that requests will always be answered. When changing DNS server settings, you’ll want to make sure that you specify at least two servers, although you can include more if you want.
