About Windows DNS Settings

DNS is an acronym for the Domain Name System. It is a client/server network communication system, in-charge of translating Internet domains and hostnames to IP addresses and vice-versa.

Imagine the DNS as a directory keeping records of IP addresses and converting them as and when required. To ensure that DNS servers are constantly in service, there are databases distributed across the world that store names and last-known address information for all public hosts on the Internet.

How DNS Works

There are two ways in which DNS provides services to quench your needs. These include:

  • Forward DNS Lookups – When you click on a website link or enter the website link in your browswer, the requests are sent as forward DNS lookups. These requests return an IP address from the server which your browser identifies converts into the beautiful webpage as it is.
  • Reverse DNS Lookups – Reverse DNS Lookups work in complete contrast to Forward DNS Lookups. In this way, you send the IP address of a host that you want to traverse to and the DNS server returns a name back to you.

Important DNS Servers

By default, your computer automatically obtains the required DNS Settings from your network connection. However, you might want to connect to a different DNS server of your choice. Here are 7 popular DNS servers and their IP addresses that you should know about:

  1. Google Public DNS Server                  – and
  2. Norton ConnectSafe                           – and
  3. OpenDNS                                 – and
  4. Level3                                                – and
  5. Comodo Secure DNS                          – and
  6. SafeDNS                                  – and
  7. DNS.Watch                               – and

Changing Important DNS Settings

Now that you’re acquainted with these important DNS Servers, you might want to use them instead of the default DNS Settings provided. There are three ways in which this can be accomplished:

  1. Changing DNS Settings With The Control Panel
  2. Changing DNS Settings With The Command Prompt
  3. Changing DNS Settings With The Settings Panel

Let’s go through each of these ways and you can choose your desired way for changing these DNS Settings.

Changing DNS Settings With The Control Panel

Here are the steps for changing the DNS Settings via the Control Panel:

  1. Launch Control Panel and traverse to the Network and Internet option.
  2. Choose Network and Sharing Center and click on the Change Adapter Settings.
  3. Right-click the interface connected to the Internet and select Properties.
  4. From here, select Internet Protocol Version 4 (TCP/IPv4) and click on Properties.
  5. Click on the Use the following DNS Server addresses option.
  6. Type in the IP addresses of one of the servers provided above.
  7. Once you’re done, click on the Ok button and the Close button.

And you’re good to go.

Changing DNS Settings With The Command Prompt

The Command Prompt allows you to accomplish the same task in an easier way. Here are the steps how:

  1. Start your Command Prompt and run it as administrator.
  • Type command netsh for networking settings in the prompt and hit Enter.
  • Now, type the command: interface ip set dns name = “ADAPTER NAME” source = “static” address = “X.X.X.X”. In place of the ADAPTER NAME use the interface name that you identified in Step No. 4, and change X.X.X.X to the preferred DNS server IP address from the ones mentioned above.
  • Once you’re done setting the primary IP address, it is the time to set the secondary IP address. Follow the same steps with just a few changes. Just use the command: Just use the command: interface ip add dns name = “ADAPTER NAME” addr = “X.X.X.X” index = 2.

Once you’re done with these steps, Windows will automatically configure the network settings to use the new DNS settings.

Changing DNS Settings With The Settings

The Settings provide the final way for changing the DNS settings. Now, this process is quite similar to the Control Panel process, particularly because all the steps are almost the same. Here are some of the steps:

  1. Open Settings, click on Network & Internet, and select your Internet connection.
  2. Selecting opens a new windows with another set of options. Choose IP Settings.
  3. Click on Edit IP Settings options and select the Manual option.
  4. Toggle on the IPv4 switch.
  5. Now set the IP addresses within the Preferred DNS and Alternate DNS options.
  6. Click on the Save button.
  7. For best results, it is advised that you restart your computer to allow changes to take place.
