Hello,

I have several ranges of IP’s being put into iptables.
The IP ranges look like this:
62.29.0.0/17
62.68.192.0/19
62.108.64.0/19
62.244.192.0/18
62.248.0.0/17
77.67.128.0/17
77.72.184.0/21
77.73.216.0/21
77.75.32.0/21
77.75.216.0/21
77.79.64.0/18
77.92.0.0/19
77.92.96.0/19
77.92.128.0/19
77.223.128.0/19
77.245.144.0/20
78.40.224.0/21
78.111.96.0/20
78.135.0.0/17


I am blocking a specific IP from the firewall as logged in messages
71.74.56.125.
In looking at each block of ip’s and using a CIDR calculator I can’t figure
out what range it’s really coming from.  The list I have is pretty huge.
Is there a tool or a way to ask iptables what rule it matches?  Based on all
my calculations I don’t have anything declared that would block that IP.

Thanks!
