#  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
