Troubleshooting: How to Flush the DNS Cache
You've made some changes to your website's DNS file and verified that DNS propagation has completed, but your website isn't working as expected.


When you visit websites, your browser keeps track of which sites you've visited. Have you noticed that when you return to a website it seems to load a little faster? This is because your browser has saved or 'cached' the location of the site , so the browser doesn't have to find the location of the server where the site is hosted.

The cache contains a temporary record of your website's IP address, hostname, and A or AAAA DNS record.

Your website's DNS cache works in a similar way by storing croatia phone number data information about your site. If you're having problems with your website, this could be because the DNS cache has become corrupted or the data it contains hasn't been updated properly.

Flushing simply means emptying the DNS cache. This can solve many of the problems you may encounter when managing your website. The way you flush the DNS cache is different for each operating system (OS). Follow the steps below for the operating system you use:

Windows
MacOS
Linux
Chrome
Clearing your website's DNS cache is a good idea, particularly if you're changing your website's host. If you're making changes to your DNS A record, for example, clearing the cache will ensure that you're seeing the correct version of your site when you check that it loads and displays correctly when the migration is complete.

DNS Security
Making your WordPress site as secure as possible is vital. Visitors to your site want to be confident that they can use your site safely. In the context of DNS security, DDoS (Distributed Denial of Service) attacks are a present danger that needs to be paid close attention to.
