These DNS servers are often based close to the customer and provide a low response rate and is reliable enough. It is common for ISPs to have their proper DNS servers for their customers. It should be good to also check the graphs displayed below this result, such as the mean response duration or the response distribution chart for the first 200ms. If you are in a hurry, go to step 4 to set these new nameservers as your default.Ĭool! So Namebench has now automatically determined which three nameservers are the fastest and nearest and thus the recommended nameservers for your internet connection. The recommended configuration is displayed in the top right corner. This is a simple HTML page which is stored locally and will display the results of the DNS benchmarking. Once Namebench has finished its testing (it should take no more than 10 minutes – this depends on the query data source and your internet connection), a webpage with the results should open. Your third step is to analyse the results. Click on ‘Start benchmark’ and sit back for a few minutes so the tool can start its benchmarking! Step 3 – Analyse the results The tool will benchmark how long it takes for each of the DNS servers tested to get the IP address. This means that the top 2,000 most visited websites’ will be resolved to their IP addresses. You will be probably be fine if you just choose ‘Top 2,000 Websites (Alexa)’. Now you can define the query data source. In case these DNS servers are defined in your router’s configuration, the nameserver that should be displayed is 192.168.1.1 or the private IP address of your router. It is also possible you defined your nameservers on the device you are using. Often, your DNS servers are defined within your router. Step 2 – Start the benchmarking of your DNS server(s)
