Every time I see this question it' usually related to a fundamental misunderstanding of IPv6 and the attempt to apply v4 logic to v6.
That said. Any size prefix will likely work and is even permitted by the RFC. You do run the risk of encountering applications that assume a 64-bit prefix length, though. And you're often crippling the advantages of IPv6.
Just curious: What are the advantages you're referring to?
1. Sparse addressing 2. SLAAC 3. RFC 4193 Privacy Addressing 4. Never have to worry about "growing" a subnet to hold new machines. 5. Universal subnet size, no surprises, no operator confusion, no bitmath. There are probably others. Owen
