        # DNS Speed Tester

This is an R script to test the speed (in milliseconds) of some of the public DNS resolvers from your Internet connection. Helps you choose a suitable DNS resolver should you wish to change from your ISPs DNS resolver.

These public DNS resolvers are checked by default (*Modify the script to add your preferred DNS resolvers*):

 * adguard - *176.103.130.132*

 * cleanbrowsing - *185.228.168.168*

 * cloudflare - *1.1.1.1*

 * comodo - *8.26.56.26*

 * DNSadvantage - *156.154.70.1*

 * DNSWatch - *84.200.69.80*

 * DYN - *216.146.35.35*

 * freenom - *80.80.80.80*

 * google - *8.8.8.8*

 * level3 - *4.2.2.1*

 * neustar - *156.154.70.3*

 * norton - *199.85.126.10*

 * opendns - 208.67.222.222

 * opennic - *176.126.70.119*

 * quad9 - *9.9.9.9*

 * safeDNS - *195.46.39.39*

 * verisign - *64.6.64.6*

 * yandex - *77.88.8.7*

# Dependencies 

You may need to install following for the script to work.

+ R [from CRAN](https://cran.r-project.org)

+ ```dig``` **D**omain **I**nformation **G**roper - [More on wikipedia](https://en.wikipedia.org/wiki/Dig_(command)). Dig is part of [bind](https://www.isc.org/downloads/bind/) package.

  + ```dig``` is pre-installed on MacOS but for linux system it can be installed using:

```sh

 $ sudo apt-get install dnsutils

```

# Usage

``` sh

 $ git clone https://github.com/dchakro/DNSSpeedTester.git

 $ cd DNSSpeedTester

 $ Rscript ./DNSSpeedTest.R

```

The script generates the data as a TSV (example below).

+ TSV converted to Markdown table using this tool: https://github.com/donatj/CsvToMarkdownTable:

+ This project was inspired by [DNSperftest](https://github.com/cleanbrowsing/dnsperftest/) and was written in R from the ground up to query DNS resolvers using dig, then calculate the mean and standard deviation for the DNS queries, sort the output based on average response time and subsequently, write the output to a TSV file.  DNS Speed Test also includes more DNS resolvers and attempts to resolve the address three times.
