nstest

This script is used to test the response time of dns servers.

Prequisites

dnspython 2.0.0 or more

python3 -m pip install dnspython
#In case you need to upgrade add the --upgrade argument

Usage

At the beginning of the script are a list of sites used to test the DNS resolvers (feel free to use what you want):

sites = [\
        "wiki.squirrelsystem.fr",\
        "www.justgeek.fr",\
        "www.yahoo.co.jp",
        "mail.google.com",\
        "store.steampowered.com",\
        "pornhub.com",\
        "rznet.fr"\
        ]

There also is a list of DNS servers (use a list suited for your needs):

dnsservers = [\
        "1.1.1.1",\
        "8.8.8.8",\
        "208.67.222.222",\
        "156.154.70.1",\
        "199.85.126.10",\
        "8.26.56.26",\
        "80.67.169.12",\
        "9.9.9.9",\
        "64.6.64.6",\
        "37.235.1.174"\
        ]

Simply call the script and it will give you an output based on the average answer time of the server :
