First of all, thank you for implementing this new feature so quickly! I began using the feature, and at first it was working normally, but then it began working both intermittently and abnormally. For example, it would have no effect on certain urls (such as 172.25.12.2). And sometimes when it did work, a url that I previously corrected would return to being a url. I believe that you can duplicate this by creating a series of numbers like the following, and then start removing each url from top to bottom.
1.1.1.1
2.2.2.2
3.3.3.3
4.4.4.4
5.5.5.5
Please let me know if you need more information.
