RE: Determining the country of orgin for IP address(es)

[dendler () idefense com]

In the wake of the September 11 terrorist attacks, 
iDEFENSE compiled a list of IP addresses for our 
clients mapped to 80 specific countries by spidering 
ARIN, APNIC, and RIPE.  These lists have just been made 
publicly available on our web site in Excel format at: 
http://www.idefense.com/Intell/CI022702.html

Hope you and others on this mailing list find them 
useful.

Subject: Determining the country of orgin for IP 
address(es)


Hello,
I am looking for a list or a tool that will allow us to 
determine and
possibly block IPs from other countries.  I am aware of 
Geo-IP, are
there any others?
I initially understood, please correct me if I am 
wrong, that when IPS
were originally given out there was a number scheme in 
regards to
countries. If so, is there a huge check/cross listing?

Thank you,
Brian Nichols
