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¶
