In advanced computing you may encounter situations where you want to bind multiple IP addresses on one physical network interface. This post describes how to do it with Ubuntu Linux (should work with Debian too).

The TOC Generator Plugin does not work as it searches for HTML headings before the markup (in my case Markdown) is applied.
