How can I finf a Partial IP address to Country
 

I'm getting alot of spammers from Thailand lately. What I want know is how do I find out which countries are within a range for their IP address.

Example, my spammer is from these address:
182.52.13.191
182.52.13.176
182.52.12.202

So how do I find out all the countries with IP's range 182.0.0.0 thru 182.255.255.255 ?? (for example).

Try this:

http://www.ipaddresslocation.org/ip_...get_ranges.php

It seems like with that one you must know the country 1st. It seems like you must select Thailand (for example), and then it gives you their range.

Suppose I don't know the country, and I want to see what counties are within a certain range.
Example:
182.0.0.0
thru
210.255.255.255

I know this would like thousands of countries, but it's just an example
What I don't want to do is block 182. only to find that the US, UK, or Australia are located in that range.

Here is another example for Thailand. I can see that 182.52.0.0 thru 182.53.255.255 are all from Thailand. But lets say I want to see 182.0.0.0 through 181.50.95.255, which county is 182.0.0.0 through 182.50.80.0 ?

182.50.80.0 - 182.50.95.255
182.52.0.0 - 182.53.255.255

Is there a way on the link you sent to do this?

I'm not sure if theres going to be an easy way to do that. You've probably gotta do a two step method.

First find the country of your spammers using just about any simple WHOIS will return that.

Then you can get an entire country IP range http://www.countryipblocks.net/

But you should probably be warned that spammers IP changes just like anyone elses, so you might want to be careful blocking entire countries by ip address

Thanks for the answer. I was afraid of that.
Thanks for everyones help...
