How to Clear DNS Cache in Microsoft Edge

Microsoft Edge uses DNS to resolve the domain address to a machine-friendly IP address mapped to a web server hosting site files. The browser also stores these DNS records as a DNS cache. This avoids frequent DNS lookups and helps load websites faster in future sessions.

However, an outdated or corrupted DNS cache could lead to issues such as the website not loading, broken web pages, etc. In such cases, clearing the Edge browser’s DNS cache can help resolve the issues.

A similar feature is also available on other browsers like Google Chrome and Apple Safari, clearing the DNS cache on any device type or platform.

Note: Web browsers like Chrome, Edge, etc., have built-in DNS host and cache. You should clear your device’s DNS cache if you have a network-related problem within your system or any other application.

Clearing the DNS cache process is similar on all platforms and device types; you can learn how to flush the DNS in Edge browser on a computer, Android, iPhone, or iPad.

Flush DNS Cache in Edge Computer

The site you visit in your Edge browser records the domain address and rendered IP address in the DNS cache. If the IP address of a web server changes, your browser might be referred to the cached records and still try to connect the old IP address, which results in errors. Hence, flushing the DNS cache will resolve the connectivity issue.

Here are the steps to clear the DNS cache from the Edge on the computer:

1. Launch Edge browser on your computer device.
2. Type edge://net-internals/#dns in the address bar and hit Enter key.
   It will open the DNS lookup page within Edge.
3. Click the Clear host cache button for the Host resolver cache option.
   

After clearing the host cache, you can check the URL to see if it resolves to the correct IP address and open the website without issue. You can also use the Domain Lookup service available on the same page.

Note: Clearing the DNS cache won’t impact saved browsing data, stored passwords, or bookmarks. It will only reset the DNS cache of the websites you visited.

Flush DNS Host Cache in Edge Android

Like a computer browser, Edge for Android uses built-in DNS instead of relying on Android’s DNS. Hence, clearing the Android DNS cache will not affect the browser DNS cache.

If you have page loading issues, you should clear the Edge DNS host cache to resolve the same.

1. Launch the Microsoft Edge on your Android Phone.
2. Type edge://net-internals/#dns in the address bar.
3. Click the Clear host cache button in the right pane for the Host resolver cache option.
   

You can look up the domain name (browserhow.com) in the Domain field to verify the IP address before and after clearing the host cache. If the site with the issue has changed its resolving IP address, the lookup results will display the same.

Clear DNS Cache in Edge iPhone or iPad

Unfortunately, like most browsers (Chrome, Safari, etc.) running on iOS or iPadOS, the Edge browser for iPhone or iPad does not support DNS cache. If you visit the edge://net-internals/#dns in the address bar, it will result in an ERR_INVALID_URL error.

The iPhone or iPad does not have any option to flush only the DNS cache, even on the Network Settings page. However, Airplane mode is the easy way to clear the DNS cache on iPhone or iPad.

Using Airplane Mode

When you Turn On, and Off the Airplane mode, the iOS or iPadOS automatically reset the network settings along with the stored DNS cache. Here are the steps to follow:

1. Slide down to open the Control Center on your device.
2. Tap on the Airplane mode button to Turn On.
   
3. Wait for a few seconds and then Turn Off the Airplane mode.

The saved network details will be flushed, and new settings and DNS records will be recorded.

Alternatively, Rebooting the iPhone or iPad device also helps to flush the DNS cache.

Reset Network Settings

A more complex way to clear the Edge DNS cache is by using the Reset Network settings option. Here are the steps to follow:

1. Open the Device Settings app on your iPhone or iPad.
2. Tap the General settings, and scroll to the bottom to select the Transfer or Reset iPhone option.
3. Tap on the Reset command and select the Reset Network Settings option.
   

While the Reset Network Settings option is not recommended unless you have a major network-related issue, you can use the Airplane mode instead to resets the DNS cache on Edge for iPhone or iPad.

Bottom Line

The Edge browser has a dedicated DNS host storage independent of your system DNS. If there are site loading or network connectivity issues within the Edge browser, you can visit the edge://net-internals/#dns in the address bar and hit the Clear host cache option.

The DNS resolver caching is available in computer and Android browsers. However, you need to rely on the iPhone or iPad airplane mode or network settings page for flushing the same.

If the network or loading issue isn’t resolved, you can also consider clearing the Edge browser cache and cookies and clearing the DNS cache for better results.
