20 Best Alternative DNS servers

 

What is a DNS server?

 

The DNS or domain name system is a naming system used to translate domain names into IP addresses, that is, alphanumeric addresses into numeric addresses..

Domain names are easier to remember for humans and IP addresses are used by computers to establish connections between the user’s computers (client) and the computer that is serving the information (server).

These translations is a necessary step to establish connections in Internet.

 

Reasons to change your DNS configuration

 

1. Stability and speed

Some Internet service providers don’t have an stable and fast DNS service. In that case, navigating the Internet is slow and the users have problems establishing connections.

Usually, the DNS servers from your ISP are very fast and if you decide to change the DNS configuration for other reasons you should choose some other servers with a similar or smaller latency value.

The latency is the time it takes to send and receive a small information package between the user’s computer and the server. It’s measured in milliseconds and you can use a small program included in Windows called Ping to get the latency.

To run Ping you have to :

  • Open the Windows menu and select All programs.

  • Select Accessories and click on the Command prompt icon.

  • In the Command prompt window you have to type ping, followed by a space and the address that you wish to check. For example, “ping 4.2.2.2” (without quotes).

  • Press Enter and you’ll get the results. The last line shows the average time in milliseconds (latency).

 

2. Censorship

The translation of domain names into IP addresses sometimes is used to block contents for the following reasons :

  • The government considers that some contents are illegal for their citizens.

  • The local network manager considers that some contents are not appropriate for the users. For example, corporate or home networks.

Sometimes the users change the DNS configuration to bypass the censorship, sometimes to protect employees or family members from inappropriate or harmful contents.

Stop Internet censorship

 

3. Content distribution networks (CDN)

Some content providers share the server workload by using several servers in different locations across the planet. These servers form what is called a CDN or content distribution network.

The users are not aware of using a content distribution network because all of them use the same domain address to access the service, but not all of them are connected to the same server.

One way to choose which server must be assigned to each user in a content distribution network is based in the DNS servers. Depending on the user’s DNS configuration, the same domain name will be translated into a different IP address corresponding to a server of the content distribution network.

In case the assigned server from a content distribution network is overloaded, it’s possible to get a different server with better performance by changing the DNS configuration.

On other occasions, you could access a different server from the same CDN with geographically locked contents.

 

4. Privacy

Some DNS service providers and Internet service providers log all the addresses visited by the users and then they share this private information with third parties.

 

5. Ad blocking

Some DNS service providers block all the addresses from hosts identified as ad servers.

 

6. Security

Some DNS service providers add some features that improve the security of the communications with their servers :

  • DNSSEC : Protects from some attacks but it doesn’t add confidentiality to the communications.

  • DNSCrypt : Encrypts the DNS traffic between the user and the server.

 

How to change the DNS configuration?

 

A) In Windows

Every time you boot your computer, it receives the DNS configuration from the DHCS server (your router most of the times). If you want to use a different set of DNS servers then you have to customize the Windows configuration.

In Windows 7 you have to follow these steps :

  1. Open the Control panel.

  2. Click on the Network and Internet icon.

  3. Click on View network status and tasks.

  4. Click on Change adapter settings.

  5. Select the network adapter used to connect to the Internet, right click on its icon and select Properties.

  6. Select Internet protocol version 4 and click on the Properties button.

  7. Select Use the following DNS server addresses.

  8. Copy the Preferred and alternative DNS server addresses just in case you want to go back to the previous configuration at a later time.

  9. Type the new Preferred and alternative DNS server information.

  10. Click on the OK button in the two properties windows.

 

In Windows 10 you have to follow these steps :

  1. Open the Configuration.

  2. Click on the Network and Internet icon.

  3. Select Wi-Fi or Ethernet to the left.

  4. Click on Change adapter settings to the right.

  5. Select the network adapter used to connect to the Internet, right click on its icon and select Properties.

  6. Select Internet protocol version 4 and click on the Properties button.

  7. Select Use the following DNS server addresses.

  8. Copy the Preferred and alternative DNS server addresses just in case you want to go back to the previous configuration at a later time.

  9. Type the new Preferred and alternative DNS server information.

  10. Click on the OK button in the two properties windows.

 

B) In the router

By setting a new DNS configuration in the router you are setting it in all devices connected to it when they boot. This can be useful when you wish to block inappropriate contents to all the users, to block ads in all devices, etc.

Every router brand and model has a different way to set the DNS configuration so it’s not possible to give all the step-by-step guides in this article.
