404 pages in ASP.NET MVC

I am building my first ASP.NET MVC website and I am trying to figure out how to implement a 404 page.

Should I create a controller called "404Controller?"? If so, how can I then register this controller with IIS so that it redirects 404s to this page? In addition, in a situation where something is not found (for example, in the database) by any other controller code, how would I redirect the request to my 404 page?
