DNS recursive query vs. Iterative query

The goal of DNS is to resolve a fully qualified domain name (FQDN) to an IP address. The process is called name resolution.
In this video I will use one example to demonstrate the whole process how name resolution is done. At the same time, the difference between recursive query and iterative query is explained.

Crystally clear! What an amazing teacher!

[@sunnyclassroom24]

Thanks a lot.

[@joneslt]

Agreed! People who understand technology are a dime a dozen. People who can clearly explain it like this is extremely rare

[@brandonhunter3036]

I always forget the difference between “iterative” DNS query types and “recursive” DNS query types, but this video was a very helpful refresher.

[@sunnyclassroom24]

thanks.

[@zidanetribal2343]

[@jaisonthomas1042]

For years, I was trying to memorise the working of recursive and iterative querries. You really helped me :)

[@sunnyclassroom24]

[@vladislavkaras491]

Really great video, I must say! I only have one thing to say, that host becomes before the DNS cache (if you already have something in cache, and you write same domain name in the host file, but with different ip, the computer listens to the host file first).
