DNS stands for Domain Name System. It is a system that translates domain names, which are easy-to-remember names like google.com or amazon.com, into IP addresses, which are unique numerical identifiers assigned to every device connected to the internet. DNS servers are responsible for this translation process, and they are crucial for enabling users to access websites and other resources on the internet using domain names instead of having to remember the corresponding IP addresses.
What Is DNS?
DNS stands for Domain Name System. It is a system used on the internet to translate human-readable domain names (such as google.com) into the IP addresses (such as 172.217.164.78) that computers use to identify each other and communicate.
When a user
types a domain name into their web browser, the browser sends a request to a
DNS resolver to look up the corresponding IP address. The resolver then checks
its cache or sends a query to one or more DNS servers to obtain the IP address.
Once the IP address is obtained, the resolver returns it to the browser,
allowing the browser to connect to the website.
DNS is a
critical component of the internet infrastructure, allowing users to easily
navigate and access websites without needing to remember numerical IP addresses.
It also allows website owners to change the location of their servers or web
hosting services without affecting the accessibility of their website to users.
What DNS Am I Using?
Well you can
use online tools such as "What's My DNS Server?" or "DNS
Checker" to check what DNS server you are using. These tools will display
your public IP address and the DNS server that your device is currently using.
What About Custom DNS?
Custom DNS refers to the use of a DNS server other than the default DNS server provided by your Internet Service Provider (ISP). Custom DNS can be set up for various reasons, such as improving website loading times, blocking access to certain websites, or accessing websites that are blocked in your region.
Check DNS On Windows
You can check the DNS server(s) currently being used on your Windows device by following these steps:
1. Press the Windows key + R to open the Run dialog box.
2. Type "cmd" and press Enter to open the Command Prompt.
3. In the Command Prompt window, type "ipconfig /all" and press Enter.
4. Look for the "DNS Servers" entry in the output. This will show you the IP addresses of the DNS server(s) that your device is currently using.
Alternatively, you can check the DNS server(s) using the Windows Network and Sharing Center. Here's how:
1. Right-click on the network icon in the system tray and select "Open Network & Internet settings."
2. Click on "Change adapter options."
3. Right-click on the network adapter you want to check and select "Status."
4. Click on the "Details" button.

Check DNS Server On Android
You can
check the DNS server currently being used on your Android device by following
these steps:
1. Open the
"Settings" app on your Android device.
2. Tap on
"Wi-Fi" or "Wireless & Networks" (depending on your
device).
3. Find the
Wi-Fi network you are connected to and tap on the gear icon next to it.
4. Scroll down
and tap on "Advanced" or "Advanced settings."
5. Look for the
"DNS" or "DNS settings" option and tap on it.
6. If
"Automatic" is selected, you will see the DNS server(s) provided by
your network or ISP. If "Static" is selected, you will see the DNS
server(s) you have manually entered.
Alternatively,
you can use a third-party app to check the DNS server currently being used on
your Android device. There are many apps available on the Google Play Store
that can display your device's network information, including the DNS server.
Some examples include "PingTools Network Utilities," "Network
Info II," and "IP Tools: Network Scanner."
Check the DNS Server Of the Router
You can
check the DNS server(s) configured on your router by following these steps:
1. Open a web
browser on a device that is connected to the router's network.
2. Enter the IP
address of your router in the address bar and press Enter. The IP address of
the router can usually be found on a sticker on the router itself, or in the
manual that came with the router.
3. Enter the
username and password for the router. If you haven't changed these from the
default settings, they can usually be found in the manual or on the router
itself.
4. Once you are
logged in to the router's web interface, look for a section labeled
"DNS" or "DNS Server." The location of this section may
vary depending on the router model and firmware.
5. In the DNS
section, you should see the IP addresses of the DNS server(s) configured on the
router.
Note that
some routers may be set up to automatically use the DNS server(s) provided by
your ISP, in which case the DNS server(s) displayed on the router's web
interface will be the same as those provided by your ISP.
