Suppose I type in the website  www.youtube.com. The computer first asks a local domain name server (DNS) what the IP address of this website is. If it can't find it, it then asks the root server, etc. This is recursive querying. How does DNS work if there is no recursive querying? Is the root server the only one that is used to find the IP address of the website?
