Wrong.

CIDR hierarchy (available within ASes) has strong correlation
to network topology that locations below certain hierarchy
are strongly connected, which is why, from out side of the locations,
packets may be routed only looking at that levels of hierarchy.

OTOH, hierarchy of domain name represents organizational
structure with weak relationship to topology. No internal connection
can be expected and it is not useful for proxy routing.

They are dissimilar.
