  • 1. IPv4 Depletion and IPv6 Deployment Cisco World IPv6 Launch Nathalie Trenaman RIPE NCC TrainerTuesday, June 5, 2012
  • 2. RIPE and RIPE NCCTuesday, June 5, 2012
  • 3. RIPE / RIPE NCC RIPE Open community Develops addressing policies Working group mailing lists RIPE NCC Located in Amsterdam Not for profit membership organisation One of five RIRs 3Tuesday, June 5, 2012
  • 4. The five RIRs 4Tuesday, June 5, 2012
  • 5. IPv4?Tuesday, June 5, 2012
  • 6. IANA IPv4 Pool 40% 30% 20% 10% 0% 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 6Tuesday, June 5, 2012
  • 7. IPv4 Depletion Worldwide IPv4 Pool in /8’s 6 5 4 3 2 1 0 AfriNIC RIPE NCC LACNIC ARIN APNIC 7Tuesday, June 5, 2012
  • 8. RIPE NCC IPv4 Pool 8Tuesday, June 5, 2012
  • 9. Allocations From the Final /8 • When the RIPE NCC reaches the final /8: – Every member can get a /22 (1024 addresses) – Only if they already have IPv6 addresses – Only when there is justified need • Current policy does not allow for PI assignments – Policy proposal 2012-04 under discussion – Intends to allow for PI assignments 9Tuesday, June 5, 2012
  • 10. Transfer of IPv4 Allocations • Policy 2007-08: Allocation Transfer Policy – Don’t buy your IPv4 on eBay! – Transfer unused allocations to another member – Minimum allocation size /21 – Evaluated by RIPE NCC – Update in RIPE Database http://www.ripe.net/lir-services/resource-management/listing 10Tuesday, June 5, 2012
  • 11. IPv6!Tuesday, June 5, 2012
  • 12. IPv6 Address Distribution /3 IANA /12 RIR /32 LIR /48 /56 /48 End User Allocation PA Assignment PI Assignment 12Tuesday, June 5, 2012
  • 13. IPv6 Ripeness • Rating system: – One star if the LIR has an IPv6 allocation – Additional stars if: - IPv6 Prefix is announced on router - A route6 object is in the RIPE Database - Reverse DNS is set up –A list of all 4 star LIRs: http://ripeness.ripe.net/ 13Tuesday, June 5, 2012
  • 14. IPv6 RIPEness: 8201 LIRs 1 star 14% 2 stars 6% 3 stars 11% No IPv6 51% 4 stars 18% 14Tuesday, June 5, 2012
  • 15. IPv6 Enabled ASes in Global Routing • Any country or region possible, updated daily http://v6asns.ripe.net 15Tuesday, June 5, 2012
  • 16. Getting an IPv6 allocation • To qualify, an organisation must: - Be a member of the RIPE NCC - Have a plan for making assignments • Minimum allocation size /32 • Allocation size is based on customer numbers and growth, not on transition technique! 16Tuesday, June 5, 2012
  • 17. Customer Assignments • Every “end site” can be assigned up to a /48 without prior approval of the RIPE NCC – That is 65536 subnets per site – If they need more, ask for approval first – Or make a sub-assignment • Assignments for your own infrastructure – /48 per Point of Presence – One additional /48 for the core network 17Tuesday, June 5, 2012
  • 18. Provider Independent Assignments • PI assignments in IPv6 – Must have a contract with a member of RIPE NCC – Minimum assignment size is a /48 – More if there is justified need • No sub-assignments are allowed – Not even a single address for the connection – If you have customers, you can not use PI for them 18Tuesday, June 5, 2012
  • 19. Creating an Addressing PlanTuesday, June 5, 2012
  • 20. Why Create an IPv6 Addressing Plan? • Mental health during implementation(!) • Easier implementation of security policies • Efficient addressing plans are scalable • More efficient route aggregation 20Tuesday, June 5, 2012
  • 21. IPv6 Address Management • Your Excel sheet might not scale – There are 65.536 /48s in a /32 – There are 65.536 /64s in a /48 – There are 16.777.216 /56s in a /32 • Find a suitable IPAM solution 21Tuesday, June 5, 2012
  • 22. Administrative Ease • If possible assign on 4 bit boundaries – Matches a hexadecimal digit – Easier to read and remember – Aligns with reverse DNS zones • Possibly follow the structure of the network or organisation – Can aid in access control and troubleshooting 22Tuesday, June 5, 2012
  • 23. Making Customer Assignments • Don’t be too conservative • Assign a generous amount of subnets • /56 is a popular size for residential – Allows for 256 subnets – Future proof • Business customers often get a /48 • You don’t want to renumber later on 23Tuesday, June 5, 2012
  • 24. “Smart” Addresses Example • Assume you got 2001:db8:1234::/48 • In your subnet 2001:0db8:1234:XYZZ::/64 –X can represent a location, i.e. “north building” –Y can represent a function, i.e. “workstations” – ZZ can represent the specific subnet (number) • 2001:0db8:1234:1316::/64 could mean: – South building, printers, area 16 (accounting) 24Tuesday, June 5, 2012
  • 25. Need Help Making a Plan? • Surfnet, the Dutch NREN, prepared a document – How to divide your /48 on a site? • Available in English on our website https://www.ripe.net/lir-services/training/material/IPv6-for-LIRs-Training-Course/IPv6_addr_plan4.pdf 25Tuesday, June 5, 2012
  • 26. Deploying IPv6 • IPv4 and IPv6 are not compatible by design – Allows to deploy IPv6 without breaking things • To communicate freely a computer needs both an IPv4 and IPv6 address – This is known as “Dual Stack” • It is all about adding IPv6 to your network – IPv4 will remain as well for now 26Tuesday, June 5, 2012
  • 27. Make Sure You Have a Plan • In the near future you need IPv6 • Take a phased approach: – Make an inventory of what you need – When purchasing add demand for IPv6 support – Identify which elements need replacing – Plan every step and test it before deploying • No longer depend on IPv4 alone 27Tuesday, June 5, 2012
  • 28. RIPE-554 Document • “Requirements for IPv6 in ICT Equipment” • Best Current Practice describing what to ask for when requesting IPv6 Support • Useful for tenders and RFPs • Originated by the Slovenian Government – Adopted by various others (Germany, Sweden) • Updated yesterday! 28Tuesday, June 5, 2012
  • 29. IPv6 Act Now! (but take it slowly)Tuesday, June 5, 2012
  • 30. Questions?Tuesday, June 5, 2012
