I think i did not make myself clear.  The corrections off-list are 
valid..:)  However the modems are accessed by the providers using 
RFC1918 space and not public IP space.  This is true it does not mean 
they are natting the users..however they are using large amounts of 
RFC1918 space to either save address space in general or save the costs 
associated with the additional address space they would consume if they 
did not use the RFC1918 space.
