Why do you need to run a DNS server? My IP only changes once every few years with Comcast. I use one of the many free DNS services available online (been w/zoneedit for almost 2 decades) and set it manually when it does change. But they also support dyndns that most home routers have options to use for updates.
Most webservers are very secure when they're not running php and mysql too. They have far less of a security problem than a browser executing arbitrary javascript and require updating only once a year or two, if at all.
