Fix your DNS Server problems by using Public DNS servers
Most of us use the default dns server settings provided by our ISP and we don’t bother about it. So, very often we face problems and run into errors like ‘cannot find sever’ because the dns server of your ISP is unable to complete the request. It is a fact that ISP dns servers are not always reliable and you can face the internet connectivity issues very often.
What is DNS Server ?
A DNS or Domain Name Server is a computer which is registered to join the Domain Name System. A DNS server runs special-purpose networking software, features a public IP address, and contains a database of network names and addresses for other Internet hosts.
Solution to DNS not Working Error
So, what to do if your ISP dns server is not responding well? The solution to this problem is to use public dns servers for your computer. You can make these changes in the dns server settings in ‘Change adapter settings’ under ‘Network and Sharing Center’ and specify the new dns server settings there. Also clear the dns cache by using ‘ipconfig/flushdns’ command and start using your internet as always. After specifying the new settings you can feel that the websites are now loading very swiftly.
