IPCheck: Allow only certain IP Address to access your DotNetNuke Module

It may be desirable to allow access to a DotNetNuke module to only certain IP Addresses. The following module provides code that can be used to implement such a requirement.

The module compares the IP Address of the current visitor to a list of IP Addresses and permits or denies access.

 

Administrators can enter allowed IP Addresses. "*" can be used to enter entire IP Address blocks.

You can dowload the module here:

Note: I did not use Linq because I wanted to make the sample simple, however had I used Linq to SQL for the data access layer and Linq to objects to match the IP address I would have only used a fraction of the code with performance a magnitude more efficient (I would not have the constant looping through the collection to match the IP address).

It took me 8 times longer to code this than it would had I used Linq. I am fairly certain this will be the last example I post that does not use Linq.
