What Is the DNS Server IP Address?

//

Scott Campbell

A DNS server IP address, also known as a Domain Name System server IP address, is a unique identifier assigned to a DNS server. The DNS system is responsible for translating domain names into IP addresses, allowing users to access websites by typing in easy-to-remember names instead of complicated numerical addresses.

What is the purpose of a DNS server IP address?

The primary purpose of a DNS server IP address is to facilitate the translation of domain names into their corresponding IP addresses. When you enter a website’s URL into your web browser, your computer sends a request to a DNS server to obtain the IP address associated with that domain name. This allows your computer to establish a connection with the correct web server and retrieve the requested web page.

Types of DNS server IP addresses:

There are two main types of DNS servers: authoritative and recursive.

Authoritative DNS servers:

An authoritative DNS server provides answers to queries about domain names within specific zones. These servers are responsible for storing and maintaining the official records for a particular domain or set of domains. When someone requests information about a specific domain, an authoritative DNS server responds with the corresponding IP address or other relevant data.

Recursive DNS servers:

A recursive DNS server helps resolve queries by making requests on behalf of clients. These servers do not store specific domain records but instead fetch them from authoritative DNS servers. When you enter a URL into your web browser, your computer typically sends the query to a recursive DNS server, which then performs all necessary steps to obtain the final answer.

How do you find out your current DNS server IP address?

To determine your current DNS server IP address, you can use command-line tools or check network settings on your device.

If you’re using Windows:

  1. Open Command Prompt by pressing Windows + R and then typing “cmd”.
  2. In the Command Prompt window, type “ipconfig /all” and hit Enter.
  3. Look for the “DNS Servers” line to find your current DNS server IP address.

If you’re using macOS:

  1. Open Terminal by going to Applications > Utilities > Terminal.
  2. In the Terminal window, type “scutil –dns” and hit Enter.
  3. Look for the “nameserver” entries to find your current DNS server IP addresses.

If you’re using Linux:

  1. Open a terminal window (Ctrl + Alt + T).
  2. In the terminal, type “nmcli dev show | grep ‘DNS'” and hit Enter.
  3. Your current DNS server IP addresses should be displayed.

Changing your DNS server IP address:

Sometimes, it may be necessary or advantageous to change your DNS server IP address. This can be done through your network settings.

In Windows:

  1. Open Control Panel and go to Network and Internet > Network and Sharing Center.
  2. Click on “Change adapter settings” on the left-hand side.
  3. Right-click on your active network connection and select “Properties”.
  4. Select “Internet Protocol Version 4 (TCP/IPv4)” and click on “Properties”.
  5. Select the option to use a specific DNS server address and enter the desired IP address(es).

    In macOS:

      • Click on the Apple menu and go to “System Preferences”.
      • Click on “Network”.
      • Select your active network connection on the left-hand side.
      • Click on “Advanced”.
      • Go to the “DNS” tab.
      • Add or remove DNS server IP addresses as desired.

      In Linux:

        • Open a terminal window (Ctrl + Alt + T).
        • Edit the “/etc/resolv.conf” file using a text editor like nano or vim.i

          Remember to save your changes after modifying the DNS server IP address in your network settings.

          In conclusion, a DNS server IP address is an essential component of the Domain Name System, responsible for translating domain names into their corresponding IP addresses. Understanding how DNS servers work and how to find or change their IP addresses can help troubleshoot network issues and improve internet performance.
