How To Configure Router As Dns Server?

Domain Name Server (DNS) is used to translate domain names to IP addresses so that your web browser can load the web pages easily and quickly. It is also necessary so that people use the domain names instead of the IP address of the servers. Some of the Cisco and Linksys router models let you convert them as a DNS server. On this web page, we will show you how to configure router as DNS server. The Linksys router has a feature called DNS Local Database that lets you search and select the Internet service much faster.

Configuring a Cisco Router as DNS server

In the section below, we’ll be configuring the Cisco router (192.168.0.2) with DNS Service (192.168.0.1). Two PCs xxxx and yyyy with IP addresses 192.168.0.3 and 192.168.0.4, and a fileserver with IP address 192.168.0.5 are used.

  • Step 1 :Initially, on your Cisco router, enable the DNS service and domain lookup using the commands mentioned below.
  • R1# configure terminal

    R1(config)# ip dns server

    R1(config)# ip domain-lookup

  • Step 2 :Now, configure your Cisco router with a public name server. To do so, use the command mentioned below.
  • R1(config)# ip name-server 4.2.2.2

  • Step 3 :Once you configure it, the communication between the network devices and the router takes place directly.
  • Step 4 :For example, if a device on the network sends a DNS request, then it will be transmitted directly to the router.
  • Step 5 :After checking the request, the router will send the query to the DNS server over the Internet and the destination’s IP address is sent back to the requesting device.
  • Step 6 :Now, configure router as DNS server with your hostnames. To do so, use the command mentioned below.
  • R1(config)# ip host fileserver 192.168.0.5

    R1(config)# ip host xxxx 192.168.0.3

  • Step 7 :After completing the above steps, you need to configure your workstations and file servers to use the router’s IP address as the DNS server.
