If || ! echo "$samples"|egrep -q "+" thenĮcho " newline separated list of DNS server IP adresses"Įcho " how many DNS resolution samples to take"Įcho " collect statistics about response times from list of DNS servers" I also do not see in the application or via google search an option to enable IPv6 benchmark with Googles namebench application. After it’s done, it will even offer to benchmark nearly 5000 publicly available DNS servers in the world and find the best 50 for your connection. It ships with a GUI but I prefer the usage through the CLI. Just download DNS Benchmark, launch it (no installation required), select the Nameservers tab, and click Run Benchmark. But before you pick a public DNS server, remember that it’s a public connection, unencrypted, and therefore liable to exposure to third parties. The config files are at /etc/namebench/ while certain lists that are used by the program are here: /usr/share/namebench/data/. 19 best public DNS servers to use today Detailed list Now that you know why you want to use a free public DNS server, let’s move on to the best options to use today. You can install it on any Ubuntu-like Linux with sudo apt-get install namebench.
I am trying to perform the same benchmark for IPv6 DNS servers as the the applications listed in my post do for IPv4 DNS servers. Namebench is an open-source DNS benchmark utility listed at Google Code Archive.
I wrote little nice script to evaluate connection to DNS servers: cat >test_dns_list_speed.sh I appologise, I am not sure how to make my statement any more clear.
