Yup! Static IP (for the un-tech-savy) may have a higher potential for issue that Dish would have to support.

Tivo, Xbox, etc. all support Static with a settings menu. I use static on all my equipment for a few reasons. However, I did activate my DHCP and allowed 1 connection well above the range of my static and it was assigned to the 622 so I think I'm good to go.
