Blocking IP's in IIS with IISIP
Updated 11/30/2008 release history
IISIP is a simple app that makes it easy to block spammy IPs in IIS.
- Can block multiple IPs at once unlike the IIS Admin interface
- Automatically reads in "feeds" of known IPs (for example Chinese IPs or
black listed IPs)
- Easy to add your own feeds via a local txt file or URL to text file
- Works on Windows Server 2003 and Vista, both 32-bit and 64-bit
- It's free and source code is available (.NET C# all managed code)
Download IISIP
(ready to run, less than 100k, requires
.NET 2.0)
Download IISIP Source Code (compatible with VS2008 SP1)

free software I wrote in my spare time backup your metabase before using.

Integrated very helpful work from George Atkins: |
|
Insert addresses under a websites root node in the metabase instead of the top level node, which caused issues when manually adding or deleting blocked ip records through the IIS Admin Interface. |
|
Correctly block actual IP ranges using subnets, instead of just a single ip address. Previously
a range such as 221.0.0.0-221.12.191.255 would only insert up to 191 for the third oct for each 221.0 to 221.12 |
