There are a numbering of things that could be done:
- Use DHCPv6 IA_NA instead of SLAAC
- Have a provisioning system that provides each host with a static address.
- Bring back EUI-64. For systems with static addresses, EUI-64 works just
  fine.
- Define yet another pseudo-random IID. This time one where the IID remains
  constant over the lifetime of the system.
