What Is DNS

DNS is the acronym for Domain Name System , our computers communicate to the web via DNS servers, by default our ISP's (Internet Service Providers) fix  DNS servers for their users , sometimes these servers may fail and you start seeing the error message "DNS look up failed" even if you have the connection established.

For example if you type www.google.com   in your browser or go to 74.125.239.41 you will end up at google home page , what happens is our DNS servers resolve the url google.com into I.P  74.125.239.41 , if your DNS server fails you can't resolve the url and you will end up with error "DNS look up failed" ,
