We’ll see how to do that, How to test the speed of various DNS Servers? – DNS Benchmarking If you are using Linux machine, then an open source package called namebench can help you to compare the speeds of various DNS servers. It means, a comparison of DNS server will be a better starting point before migrating to a different DNS service. Before changing the DNS server, you must know the speed of your current DNS server compared to other DNS servers.
It returned this, in a test run: 94. you are a regular follower of Techglimpse, then by this time you must be aware of What is DNS, How it works and how to find out IP address of DNS configured on your PC and how to change or switch to public DNS. Of course you can change the testing domain (in the example is ) and the DNS servers. dnseval.py -t A -f public-servers.txt -c10 The file public-servers.txt contains list of DNS server to query from e.g. use via Docker docker run -it -rm farrokhi/dnsdiag /bin/bash Here 10 clients + 100 queries => 1000 requests sample output Statistics:Īverage packet size: request 34, response 87Īverage Latency (s): 0.083850 (min 0.080296, max 0.091041)ĭNS Measurement, Troubleshooting and Security Auditing ToolsetĮver been wondering if your ISP is hijacking your DNS traffic? Ever observed any misbehavior with your DNS responses? Ever been redirected to wrong address and suspected something is wrong with your DNS? Here we have a set of tools to perform basic audits on your DNS requests and responses to make sure your DNS is working as you expect. -l for this duration of time (10 seconds).-s source IP address = DNS server to query from.The latest version of the dnsperf and resperf can be used with test files that include IPv6 queries. These tools are easy-to-use and simulate typical Internet, so network operators can benchmark their naming and addressing infrastructure and plan for upgrades.
Dnsperf and resperf are free tools developed by Nominum/Akamai (2006-2018) and DNS-OARC (since 2019) that make it simple to gather accurate latency and throughput metrics for Domain Name Service (DNS).
