Why Clearing DNS Cache is Important

DNS caching is the process of storing recently accessed DNS lookups on your computer or internet service provider’s server. This helps speed up the process of accessing websites that you have visited before, as your computer doesn’t have to perform a DNS lookup every time you visit. However, if the DNS cache becomes outdated or corrupted, it can lead to slow internet connection or errors when accessing certain websites.

By clearing your DNS cache, you force your computer to perform a fresh DNS lookup when accessing a website, ensuring that you have the most up-to-date and accurate information. This can help resolve internet connection problems and improve your browsing experience.
