6. IPv4 exhaustion phases
IPv4 still available.
RIPE NCC continues
distributing it

7. IPv4 Run Out Fairly
Gradually reduced allocation / assignment
periods
- 12 months (January 2010)
- 9 months (July 2010)
- 6 months (January 2011)
- 3 months (July 2011)
50% has to be used up by half-period

8. Last /8
We do things differently!
Ensures IPv4 access for all members
- 16 000 x /22 in a /8
- members can get one /22 (=1024 addresses)
- must already hold IPv6
- must qualify for allocation
/16 set aside for unforeseen situations
- if unused, will be distributed
No PI so far. May change.

10. Legacy Space
IPv4 addresses distributed prior to the RIR system
Why register?
- Benefits:
- legitimize holdership
- update reverse DNS delegation
- use membership services
- no fees!
- Risks:
legacy@ripe.net
- frozen data in the RIPE Registry
- vulnerable to hijackers

11. Additional IPv4 allocation requirements
80% must be in use
Tidy up current records
Request a list of invalid assignments
Send an IPv4 Additional Allocation request
We will audit you

12. Transfer of IPv4 allocations
Transfer unused allocations to another LIR
Minimum allocation size /21
Evaluated by the RIPE NCC

15. IPv6 in Saudi Arabia
Only 36% of LIRs have an IPv6 allocation
15

16. Getting an IPv6 allocation
Requirements:
- Be an LIR
- Plan to make assignments within two years
Minimum allocation size /32
Announcement as a single prefix
recommended

17. Getting IPv6 PI space
Requirements:
- Meet the contractual requirements
Minimum assignment size /48

18. IPv6 Allocations and Announcements

19. Extension of the minimum allocation size
Awaiting decision
Initial IPv6 allocation from /32 to /29
Enables small LIRs to deploy 6RD
