Change DNS Server in Router Settings

Instead of changing the operating system, you can also change the DNS server in your router. The advantage is that all devices connected to your network (e.g. Wi-Fi network) then use the desired DNS server and do not have to be configured individually. The way you adapt the DNS server depends on your router. Most devices, however, can be managed through an in-browser interface. You will find a URL or an IP address in the user manual or on the router, which you can enter directly into the address line of the browser. All you have to do is enter your access data (which can be found in your documentation) and then look for the domain name system settings in the menus.

What are the benefits of changing DNS server?

When you connect to the Internet through your router, the DNS server settings are automatically loaded. Typically, your ISP handles name resolution. So you don’t need to worry about the configuration. Simply connect the router to the desired devices; protocols such as DHCP then assign the necessary connection information.

This is actually a good principle, but alternatives in DNS may be more appropriate. It may be useful or necessary to change DNS server by default, especially for three reasons following:

  • Speed ​​: another DNS server may provide a speed advantage, allowingspeed up loading times. Name servers OpenDNS and the Google’s public DNS serversreputed to be particularly fast, are very popular.
  • Accessibility: if the error message “DNS server is not responding” appears instead of a website, it means that the standard server for name resolution is down. Most of the time it is a temporary problembut you can fix it immediately by changing DNS server.
  • DNS blocking: the DNS can be used for the purposes of censorship. Internet service providers then block name resolution for certain domains. By choosing another DNS server, you bypass the blocking.
