Join Timothy Pintello for an in-depth discussion in this video How DNS works, part of Deploying and Configuring Core TCP/IP Services.
- Now, let's take a look at some DNS options…and how DNS queries work.…The first type of DNS query we'll talk about…is the recursive query.…In a recursive query, a client or server…sends out a resolution request.…The DNS server receiving the recursvie query…takes full responsibility for resolving that request.…If the server has the information requested,…it will reply immediately to the client,…however, if it doesn't have the information needed…it will send out iterative queries to other servers…in order to obtain the necessary information.…
TCP/IP clients will always send out a recursive query.…An iterative query happens when a DNS server…receives a recursive query,…and it needs to send out additional queries…to other servers in order to resolve the request.…If the server does not have the information it needs…to resolve the recursive query it receives from the client,…it sends out iterative queries to other DNS servers…on the network.…The receiving servers respond with what information…they have available to them.…
