IP Address Lookups for Addresses that were Blocked by FTP Dynamic IP Restrictions
A few months ago I wrote a blog post that was titled "Merging FTP Extensibility Walkthroughs - Part 2", where I described how to merge my FTP Dynamic IP Restrictions Authentication Provider walkthrough with my FTP Provider that Sends an Email when Files are Uploaded walkthrough. The result of this code combination was a custom FTP authentication provider that provides support for dynamic IP restrictions that sends me an email every time a new IP address is blocked. I deployed this custom FTP authentication provider on one of my public-facing FTP sites when I wrote the blog post, and in the three months that I have been using that provider it has blocked 88 IP addresses.
