The University's reserves of IPv4 addresses are running low. At the current rate of assignment, approximately two years' supply remains.
- IPv6 is not going to save us - systems will require access to IPv4-only services for the foreseeable future.
- There is almost no possibility of acquiring additional IPv4 address space, certainly not without paying.
- We are unlikely to be able to recover significant amounts of address space from existing allocations - most cannot easily be relinquished.
- We cannot afford to run out entirely reserves must be retained for future expansion of the University
- Future IPv4 allocations must be limited to a maximum of 256 addresses (/24 subnets). An extremely strong justification must be required for any exception to this rule.
- The future is considerably more NAT. However this is implemented, it will bring its own challenges and incur significant (direct and indirect) costs for the University.
