# Intro:  https://blog.starryvoid.com/archives/585.html
# Build:  2021/03/22 Version 1.0.1
#
# Operating environment "Python3 dnspython"
# Install Command "pip3 install dnspython"
# About "dnspython" https://github.com/rthalley/dnspython https://dnspython.readthedocs.io/en/latest/
# About "ngx_http_access_module" http://nginx.org/en/docs/http/ngx_http_access_module.html
#
# Default Input File ./dns_read_list.txt
# One line of the configuration file is like "www.google.com#1.1.1.1#A#216.58.197.196#Annotation"
#
# Default Output File ./nginx_access_whitelist.conf
# One line of the output file is like "Allow 216.58.197.196/32;"
# There is an extra rule at the end of the configuration file "deny all;"
# And automatically reload the Nginx service "systemctl reload nginx.service"
