Yes, which is why they shouldn't use those huge prefixes. There's an existing 32-bit address space represented nicely like 8.8.8.8 or 192.168.1.2 for local. Now that we want to extend the address space for more users, the newer ones can be like 8.8.8.8.6 without messing with the existing ones.

Oh and I'd actually prefer the 65520.
