Main differences:

Anycast exists, so OSPF is essentially part of the protocol. (Theoretically, you could dispatch at random, but you probably already built an OSPF tree for v4 routing)
The addresses are strictly heirarchial, with variable-length hostmasks -- this is even bigger than CIDR, as it's assumed subnets are actually masked off of a larger subnet
(There's also some boring stuff like the checksum being dropped)
These are all features of how IPv4 networks worked in 2004, but none of them were at the IP level.
