How to clear DNS cache on Android device: 4 Ways explained!

Frustrated by slow internet on your Android phone? Your DNS cache might be the culprit. For the uninitiated, a DNS cache refers to the storage of information about every website you have visited. Cached storage enhances browsing by eliminating the need for your device to fetch information on revisited websites.

However, the DNS cache can cause connectivity issues if it is corrupted or becomes outdated. So, clearing DNS cache becomes a necessity. Below, I have mentioned some effective ways to clear the DNS cache on Android.

1. Clear DNS Cache from Google Chrome on Android

The easiest way to flush the DNS cache on Android is to remove it using net internals. It is a hidden tool that stores data logs of the websites you have visited.

You can visit the Net-internals tool on Google Chrome on Android using a command.

1. Open Google Chrome on your Android smartphone.
2. Visit chrome://net-internals/#dns
3. On this page, tap Clear host cache to clear the DNS cache on your Android smartphone.
   
   

2. Remove Cache from Google Chrome Settings

To resolve connectivity issues and get rid of DNS cache, a more direct method is to clear Google Chrome’s app cache altogether.

However, you can delete other apps cache data if necessary. All you need to do is select the app you want and follow the same steps.

If clearing the DNS cache using the Chome net internals command does not work for you, you can try this method.

1. On your Android phone, tap and hold the Google Chrome app → tap App info.
   This will take you to Chrome’s settings.
2. Select Storage & cache → Choose Clear cache.
   
   

Remember, this will remove Google Chrome’s cache but not delete your browser history or your saved bookmarks.

The above methods specifically guide you on clearing the DNS cache in the Chrome browser. However, it’s worth noting that the process varies for each app when it comes to clearing the browser cache.

Below, I’ll walk you through how to clear the entire cache on your Android phone.

3. Use Phone Settings to change DNS Server

Most users use the default DNS server provided by their ISPs. However, on Android, you can change the DNS server. This will help resolve any connectivity issue that you are facing. So for that:

1. Open the Settings app → Tap Network & internet.
2. Select Private DNS → Select Private DNS provider hostname.
3. Here, you can enter any private DNS server. For a smoother experience, you can try Google’s public DNS server. 
4. Tap the textbox and enter dns.google to set your phone’s DNS server to Google’s public DNS server.
   
   
   • Alternatively, you can also change the DNS server to Cloudflare’s DNS server. For it, enter the following in the textbox 1.1.1.1.cloudflare-dns.com
5. Finally, tap Save to confirm your choice.

4. Clear DNS Cache on Android using Termux app (for Rooted Android phones)

If you are using a Rooted Android device, you can clear the system-wide DNS cache using a simple command.

1. Install Termux and grant root access when prompted.
2. Next, run the following command in Termux to clear DNS cache on Android.
   su
ndc resolver clearnetdns wlan0/rmnet0
