    I have a question that comes to mind We assume that we have 5 records, all of them with the same domain name, and each record has a different IP Why when requesting query The Name Serverin Response brings me all five records, not one or two Is this constant in dns? Or there something that can control this? I mean two records only go not the five

    I really like this video the comparison, and the use of the transparent drawing board is ingenious. However I have a question; does the DNS resolver return the IP address directly back to your home router? or does the IP back to your ISP and then to your router? I had it in my head that all of your internet traffic went PC > Router > ISP > Internet > ISP > Router > PC If anyone has a good link as to how the traffic is sent & received plz share, Thanks

    Quick Question: Your diagram shows two-way communication between the resolver and each successive lookup server. I thought that each successive lookup server goes immediately to the next server in line until the record is found and only then returns an answer to the resolver. Can you please clarify this for me? Best

  • @pvergadia

    @pvergadia

    Ай бұрын

    Yes, your understanding is accurate. The reason I show two way arrows is that it wont go to the next lookup if it find the answer, in which case it will go back to the user without recursion from any of those intermediate steps. Hope this helps.

    If one directly enteres the host's IP address, followed by the resource path (e.g.: 123.459.77.93/about), will the request still undergo DNS resolution process?
