I created my first plugin when I created my CEO Blog. The problem is obvious: I am going to have a CEO blog where I can share my thoughts with the team frequently. I tried to write a different blog, and I found it is just impossible to maintain two. So I decided to put it on to my own personal blog.
Although most of the articles are public in nature, I do have something that I hope to disclose to the general public later. I don’t want to have complicated OAuth based verification. A simple IP based restriction is good enough. There is no simple solution so I wrote one myself.

IP Only

Restrict access only to specific IP address. Other visitors will see a message. The article is hidden from feed as well.
