Hello Scott,
Thanks for the reply. well in forum you replied to Nitesh.
Actually he posted that separately unaware that I am communicating over
here. Tough just for your reference I am telling this.
Well is it feasible to block this range 69.6.0.0 to 69.6.79.255 as it
includes 20,066 ips. Though I have noticed that almost 99% of the junk
mails are coming from this ip range.
Thanks,
Yatin.

Actually, there's an easier way. :)
If you go to
http://www.dnsstuff.com/tools/whois.ch?ip=!NET-69-6-0-0-1&server=whois.a
rin.net
(the IPWHOIS lookup for 69.6.0.0), you'll find a list of the CIDR ranges
involved:
69.6.0.0/18
69.6.64.0/20
So all you need to do is add those two ranges. There's also a CIDR tool
at
http://www.DNSstuff.com that you can use to find out that 69.60.0.0/18
is
also 69.60.0.0 netmask 255.255.192.0, and 69.6.64.0/20 is also 69.6.64.0
netmask 255.255.240.0.
Hopefully, that will save you a bit of time entering in the IP ranges.
:)
