I'm going to block two ranges using ISAPI_Rewrite. I've got this situation from a real question on HeliconTech forums.
Here are the ranges needs to block:
203.207.64.0 - 203.208.19.255
203.208.32.0 - 203.208.63.255
Please look at this simple solution:
RewriteCond %{REMOTE_ADDR} ^203\.20(?:7\.(?:[6-9][0-9]|\d{3})|8\.(?:1?[0-9]|4|5[0-9]|3[2-9]|6[0-3]))\.\d{1,3}$
RewriteRule .? - [F]
You can see I've used a single regular expression for two ranges. But amount depends from specific ranges which you need. So dear friends, this example is demonstrating that knowledge of regular expressions is very important. If there is some similarity in the specified ranges, probably it's possible to compose everything in one regular expression.
P.S.: If you need some help in the ISAPI_Rewrite rules writing, or regular expressions writing, you can describe your goals here, and I will try to help you ;)

We are working to please our customers. And now we are preparing few interesting things for them.
For ISAPI_Rewrite users we improve the documentation. I working on the articles, which describes how to use ISAPI_Rewrite with the most popular Content Management Systems.
Also we has provided FAQ for ISAPI_Rewrite.
But there is another thing, which will be more interesting for many customers. It is our new product. It must be a powerful module for the IIS web server, which has a full Apache configuration compatibility! This module looks like an Apache emulator, so it's provides a lite moving from the Apache web server to the IIS web server. You just copy your configuration files!
Now we are preparing 1st beta release of new product. It will be released soon!
