    so we can say that a DNS server is typically your phone's contact list that returns the phone number of the person you locally searched for or else presumably goes to the internet to find that for you?

    DHCP stands for Dynamic Host Configuration Protocol not Control, at least by ISO standards.

    • @Weissman52
      @Weissman52 10 лет назад +6

      ...and DNS stands for Domain Name System (not service), according to EVERY RFC!

    • @jacobcrow748
      @jacobcrow748 7 лет назад +1

      Host Names
      Domain Name Service (DNS) is the service used to convert human readable names of hosts to IP addresses. Host names are not case sensitive and can contain alphabetic or numeric letters or the hyphen. Avoid the underscore. A fully qualified domain name (FQDN) consists of the host name plus domain name.
      Domain Name System
      The Domain Name System (DNS) is basically a large database which resides on various computers and it contains the names and IP addresses of various hosts on the internet and various domains. The Domain Name System is used to provide information to the Domain Name Service to use when queries are made. The service is the act of querying the database, and the system is the data structure and data itself. The Domain Name System is similar to a file system in Unix or DOS starting with a root. Branches attach to the root to create a huge set of paths. Each branch in the DNS is called a label. Each label can be 63 characters long, but most are less. Each text word between the dots can be 63 characters in length, with the total domain name (all the labels) limited to 255 bytes in overall length. The domain name system database is divided into sections called zones. The name servers in their respective zones are responsible for answering queries for their zones. A zone is a subtree of DNS and is administered separately. There are multiple name servers for a zone. There is usually one primary nameserver and one or more secondary name servers. A name server may be authoritative for more than one zone.

    @I-did-not-ask-for-a-handle 11 лет назад

    Great video, I hopeI get the basics of how it works.
    There's just one question lingering though: why does the DNS lookup happen on servers and not on the client itself? Could the DHCP not send the addresses to the PC itself or is it more efficient to store the address information on one place then in all different places?

  • @sandys8892
    @sandys8892 11 лет назад

    Hi Eli, your videos are awesome, so much explained in such detail... I have a question....so if the DNS and DHCP are not on the same PHYSICAL server, but they are on the same network, does it still cause problems with them working in tandem?

    On Windows, type the Windows key + r, then type cmd, then type ipconfig /all, you will see your dns suffix which comes from your ISP, if its a cable provider like Comcast for example you will also be able to check your DNS IP addresses, cuz usually it is more than just one...

    So if the DNS servers have been modified and are insecure, can I write in the IP adress for the website in my firefox search-bar instead and go directly out on the internet to the website without getting rerouted by the DNS?

  • @tatolives4ever
    @tatolives4ever 11 лет назад

    Yes, I get it. Only configured DNS server can aswer a request, but if this DNS hasn't the IP requested in it's cache, so it will request to some root server that (depending on the TLD or ccTLD) will request to a "registrar" responsible for domains registration, so the registrar will point to the server that owns the registered domain.

    I wonder does 'reading configuration from hosts file' play any role in your DNS loop/workflow. Sorry for my dummy and I may miss some of your last lessons.

  • @trooper744
    @trooper744 6 лет назад

    So Eli, lets say we have a DHCP pool of 30 addresses and 30 host-names and Dynamic DNS was not configured, when it comes time to configure them are those manual entries on the DNS table or is there a pool of column a (DHCP IP addresses and Column B host names and they just get paired or dynamically assigned for a specific lease time?
    Thanks,
    Jesse
