      Which two tasks can be performed by a local DNS server? (Choose two.)

      • It gives an IP address to the localhost.
      • Data can be transferred between two devices in the network.
      • For an internal host, it can map name-to-IP addresses.
      • Forward the name resolution protocol for internal servers.
      • It can reclaim the email messages.

      Answer: The task which is performed by the DNS is it gives the TP address for domain i.e.www.xyz.com the other one is it can forward the message which is not solved in another network to give the domain name for the translation of the IP address. The information of the local device IP address is given by DHCP. The files are shared with the help of the file transfer protocol and POP is used for the reclamation of the mail messages.

      In this further topic let’s study what is DNS and how to configure it in local servers. so stay connected to the end of the topic.

      Domain name system (DNS)

      The main function of the Domain Name System is to transform the domain name such as xyz.com to the numerical value in hexadecimal which is the address for the server. For example, if the IP address is 127.0.0.0 and you act by requesting the domain name then the system will act A DNS to find the address of the server for contact.

      The devices will cache the DNS response and before the actual request the new domain visit will sustain the DNS round trip, and all this happens at the level of the OS and it is invisible to the users ISPs the security measure will handle the DNS server. And with the default router setting, you can probably depend on the ISPs.

      What is the reason to run your DNS?

      The main reason to run your DNS is that you can get control over your network, and the goal is to construct the network-level domain mappings. By designing the router to use the DNS of your awn will allow one of your devices to connect or get access to 192.168.0.101 with the help of http://web.server.

      With your DNS you can make the setting centralized at one place rather than applying them Sigle in /etc./hosts on every device.it will apply to almost everything you can connect to the network along with embedded hardware which gives s the way to modify the routing stack.

      Configuration of the local DNS server

      For the configuration of the local DNS server for DNS forwarder, you can first design the ETP DNS server IP addresses and the DNS server in the security. The steps are discussed in the following:

      • In the main menu of the security connector tap on 7.
      • Then tap on the configure local DNS server and press Enter.
      • Tap on C to continue.
      • If the configuration is shown then tap on C and edit the configuration of the Local DNS server.
      • In DNS tap on IP address and then DNS servers then tap on Enter.
      • You can add a maximum of three IP addresses then Enter D to confirm and tap on Enter.
      • Tap on Y and press the enter key for the confirmation of the modification.
      • After it taps on the random key to go back to the DNS forwarder menu.
