In practice, I would say yes.
However, theoretically, AOL may suddenly use switch your connection
to use a proxy on the other side of the country on a completely
different B class if their proxy gets congested. And if they can
do that within a country (I'm almost sure they do, or can now), they
can do it around the world :)
So in practice yes, in theory and perhaps in practice no.
