So, let’s get straight into it… 

What is DNS?

DNS, or Domain Name System, is the backbone of Internet navigation. In another way, you can look at it as an address book for the web. 

The process works like this: whenever a user types a website address in the browser, DNS translates it into an IP address which is the series of numbers used by numbers to communicate. 

DNS Cache

DNS caching has to do with storing IP translations temporarily. So, when you visit any site, the system saves its IP address in a local cache for quicker access next time. 

This indicates that instead of requesting data from the DNS server every single time, the device retrieves the information from its cache.

Introduction to Chrome.//net-internals/DNS

In addition, the www.chrome //net-internals/#dns interface provides clear insights into the current DNS settings and cache status. For instance, you can have an eye on the cached entities and identify the problematic domains that may be causing delays or errors while surfing the web. 

Why Clear the DNS Cache?

Many users do not give a second thought concerning why one may want to clear the DNS cache. From this section, you can find help to optimize the internet experience: 

Website Not Loading Properly

Imagine a scenario: where one of the websites you are trying has changed its IP address, and when you are trying to land on that particular website, your browser might connect you to the old IP stored in the cache. 

Consequently, it may not let the website load properly. To rectify this issue, clearing the DNS cache ensures that you are accessing the most updated version of the website.

Inaccessible Websites

Sometimes, you might come across a situation where the site becomes completely inaccessible for no apparent reason. 

This will definitely leave you scratching your head and wondering what’s wrong. To let you know what is wrong, the problem might be with your DNS settings or an issue with the website’s server. 

Clearing the cache resets the device’s connection and establishes a new connection. Learn about other common errors like the 502 Bad Gateway and how to fix them.

Incorrect Page Display

This is another common scenario where the page displays incorrectly or only partially loads. 

The reason behind this could be corrupt data in the DNS cache that are conflicting records for the same website. 

DNS Error Messages

Are you frequently flashed with errors like “ERR_NAME_NOT_RESOLVED”, “server not found” or “DNS_PROBE_FINISHED_NXDOMAIN”? Clearing the DNS cache will refresh the DNS settings and potentially fix any underlying issues.

Privacy Concerns
