Technically speaking, I don't think this is quite true.
It's probably a local network that consists of two hosts: the router
and the family computer which in most families is getting it's local 
address served up (assigned) by the router's DHCP server. Alternatively 
it _could_ be assigned it's own fixed address (although there'd be no 
reason for your family to do so.)
I'm guessing that what you are calling a "Comcast modem" is in fact
a modem, router, dhcp server and perhaps several other functionalities 
all built into one box.
