Routing through non-addressable space???

Routing through a cable interface that has a 10.x address as its primary ip
address would be my first guess, esp. due to the 24.x address.

int cable3/0
ip address 10.x.x.x. x.x.x.x.x
ip address public.for.cpe.equip mask.mask.mask.mask secondary

Can someone explain this trace to me. How on earth did the network 
get inserted into the last hop?

#    IP address       Host name                                Round trip
