What is the difference between a recursive query and an iterative query?
What will be an ideal response?
The difference between a recursive query and an iterative query is that a name server that is presented with a recursive query must produce an answer of some kind, whereas a name server that's presented with an iterative query can simply reply with a pointer to another name server that may (or may not) be able to provide the information requested. You would think that a name server handling a recursive query could issue its own recursive queries to pass responsibility for resolving the name request to another server. But in practice, only one server fields a recursive query and keeps issuing iterative queries until it gets a definitive answer of one kind (the IP address that matches the domain name) or another (an error message that explains why an IP address can't be supplied).
