Outstanding topic. I will mention that 10.x is typically used for private corprate address's. Were as 192.x is mainly for citizen x. Although, its private so one could use any damn # you wanted. Lets stick with the standard. Now on to topic, yes most likely bootstrap. One way to find out for sure. Get you're self a cable card and go to work with WireShark. Quietly filter. This works very well I've heard. Cable techs use WireShark alot I've heard. If Im out of line let me know, but I dont think this is illegal. You have to read the 55 page TOS. Oddly enough most traffic goes through ATT one way or another.
