Enter my new creation: IP Quail
I set out to create my own service which I could host at HenchCDN, a local CDN which aims to anycast content via several internet exchanges to be nearer to end users. I purchased ipquail.com and set it up on my two HenchCDN nodes, and after several revisions, I had a web service up and running.
Instead of using PHP, since it only needs to display the REMOTE_ADDR, I changed to using simple SSI. This ensures much higher performance. I’m using Bootstrap for simplicity, cross platform responsiveness, and to grid and style the page elements.
