No, because NAT-like solutions to perpetuate v4 only handle the client 
side of the transaction. At some point there will not be any more v4 
address to assign/allocate to content provider networks. They have seen 
the writing on the wall, and many of the largest (both by traffic and 
market share) have already moved to providing their content over v6.
