The domain name server recursor don’t need the same request multiple time. caching is responsible send the request through the web browser.


It’s very essential to all internet users how the browser sends a request to the server. that is an interesting topic for all of us. The client request a web browser. The web browser sends the request to an authoritative web server. After the web server response back to the web browser. After the client gets the request of the web server through the web browser.

Sometimes it gets an error if the request or response time has too long. The browse sends the request directly to the client that request time is too long.

But, sometimes it can be dangerous while the domain name server is failed. The attackers can be an advantage of this. That can be redirected to the client request to the malicious web server. And theft the information of us.

So, we should be avoided that web page or web server that shows the Domain Name Server failed error. we can check up the domain name server in who lookup. Where established the name server of the domain.
