    Correction, putting entries in the host file does NOT input it in any cache. DNS is always (by default on linux/windows/mac) queried 2nd, the first query will always check your host file first. You can modify the order of lookups on linux by flipping the order within the /etc/nsswitch.conf file, not sure about doing this on windows but it maybe possible in the registry somewhere.

    iirc, this is not an iterative query, ISP dns server(dc01 in your video) is a recursive server, that always manages all requests by himself and collects answers. Servers like root, and tld would either forward you or send an error. That is called iterative. Correct me if im wrong

  • @morso0

    Just Epic Videos hmmm...I agree with this. An recursive query should mean the server would forward the query to the next server and so on. Each server in the chain will await the reply and return the response to the caller. The referral back to the original client part seems inefficient. But, that would make sense in an iterative approach. Still, I am skeptical about this aspect of the video.

    You have a router with either static routes or running a routing protocol that lets devices in network 192.168.1.x /24 communicate with devices (such as DNS severs) on network 192.168.6.X /24 . That simple :)

    I have captive portal website and its extension is a "in". The authoritative name server for that website is a root server. Now an authoritative name server is a server that is giving the record to the client. What i don't understand is how can any website have its authoritative name server as a root server? Cause all the root server is doing is sending the query to a server that can do the job for you. It is not the one giving you the i.p address, but just redirecting you to the right server . Shouldn't the authoritative name server be the websites DNS servers?

    Your Internet provider DNS or any DNS servers you use will need to have the root servers configured on it. Once that is done for any recursive queries that come in, it will use the closest applicable root server
