# MENTIODNS : Check for lying DNS (France) #
#--------------------------------------------#
# Version 1.2 - Round robin on DNS_ISP_LIST #
# For each request #
# Version 1.1 - Allow resume on basename #
# Version 1.0 - Parallel process with DIG #
#--------------------------------------------#
# (c) Sacha at Aquilenet.fr part of FFDN.org #
#--------------------------------------------#
# This shity script intend to bruteforce the ISP lying DNS Servers to identify which one
# is going on Ministry of Interior Blocking page and compare the IP result from your favorite DNS server
# Use this script with the following paramters
# 1 - domain names file (file with list of domain names whithout the tld
# 2 - position number if it is not given the script will start at the begining
# If you relanch the script it will check if it has a counter for the given file to resume
# Blacklisted sites in $BLACKLIST_LOG file
# Diff ip from a domain name are in $DIFF_LOG
