I can agree with that and makes since. I do forget many people don't have the knowledge how their system actually work and for the most part don't want to know. They rather have it just work and not the how & why. As for my ISP I am on Time Warner soon to be Comcast. For my LAN setup Cable Modem <-> FreeBSD acting as Firewall/Router with three nics one connected to the CM another (10.0.0.x) handles my modern devices such as updated desktops, mobile devices, and "Smart devices" the third nic goes to another FreeBSD box (10.0.1.x) with a even heavier Firewall configuration and behind that all my legacy devices are connected. All configured without DHCP. So definitely not your standard setup but it is what happens when you have a Network Administration Degree and can't find work.
