How do I reset my DNS?

Introduction

Resetting your DNS can be a simple yet effective solution to resolve internet connectivity issues. Understanding when and why to reset DNS can save you time and frustration when troubleshooting your network settings. In this guide, we’ll explore the importance of DNS, how to reset it across various platforms, and when it might be necessary to take this step.

What is DNS and why reset it?

DNS, or Domain Name System, is the internet's phonebook, translating human-friendly domain names into IP addresses that computers use to communicate with each other. Sometimes, network issues arise due to outdated or incorrect DNS settings, causing a disruption in connectivity. Resetting DNS can help refresh these settings, potentially resolving issues such as slow browsing or inability to access certain websites.

There are several reasons why you might need to reset your DNS. For instance, if you’re experiencing a lag in your internet connection or if certain websites aren't loading properly, a DNS reset can often clear cached data and restore efficient browsing. Additionally, resetting DNS can address issues related to DNS hosting changes, ensuring that your device connects to the correct DNS servers.

How to reset DNS on Windows?

Resetting DNS on Windows is straightforward, and it can be done using the Command Prompt. Here’s how:

1. Open the Command Prompt by typing "cmd" in the Windows search bar and selecting "Run as administrator."
2. In the Command Prompt window, type the command: ipconfig /flushdns and press Enter. This command will flush the DNS cache, clearing any outdated or incorrect entries.
3. For a more comprehensive reset, you can also reset network settings by typing: netsh int ip reset and netsh winsock reset, then restart your computer.

These steps will refresh your DNS settings and can resolve many common connectivity issues.

How to reset DNS on macOS?

For macOS users, resetting DNS involves using the Terminal. Follow these steps:

1. Open Terminal, which can be found in the Applications folder under Utilities, or by searching for it using Spotlight.
2. Enter the command: sudo killall -HUP mDNSResponder and press Enter. You may be prompted to enter your administrator password.
3. This command will flush the DNS cache. If you’re using macOS Catalina or later, you might need to use sudo dscacheutil -flushcache as well.

Resetting DNS on macOS can quickly address connectivity issues and improve browsing speed.

How to reset DNS on mobile devices?

Resetting DNS on mobile devices is slightly different across platforms. Here’s how to do it on Android and iOS:

These steps can help resolve DNS-related issues on your mobile devices, improving connectivity and performance.
