1 Increasing IPv6 deployment in Indonesia APJII IDNIC OPM November 2016

2 IPv4 and IPv6 IPv4 (since 1983) 32-bit number: 2 32 = ~4 billion addresses Example: Existing supply is very nearly exhausted IPv6 (standardised 1995, revised 1998) 128-bit number: = 340 billion billion billion billion addresses Example: FE38:DCE3:124C:C1A2:BA03:6735:EF1C:683D Existing supply should/must last for many decades Functionally the same, but they re incompatible Deliberate design choice IPv6 was developed as an improvement over IPv4

3 How different are they? IPv4 (Oil) IPv6 (Electric) As a passenger you don t need to know if the car you are driving is electric or gas powered. As a driver you do need to know a bit about the difference. As a mechanic, you need to know a lot, because they are different under the hood. As a road engineer, you also don t need to know. As a petrol station, you better get used to the idea that times are changing!

4 How different are they? Both protocols can be used at the same time on the same network without interference, but they can t communicate each other without network address translation IPv6 can be retrofitted into existing networks without breaking or removing IPv4 Devices can choose which protocol to use Depending on the capability of the other device its communicating with When both available, use IPv6

5 IPv4 exhaustion IANA pool fully distributed in as of 10 Nov 2016

6 Remaining IPv4 space /8 blocks AFRINIC APNIC ARIN LACNIC RIPE NCC Allocated Available As of 30 September 2016

7 Short term solution: NAT Internet Phone Network NAT PABX ? Extn 202

8 NAT at the edge The Internet /24 Network NAT* *Network Address Translation at home router, hotspot, etc

9 Carrier Grade NAT (CGN) CGN IPv4?

10 Double NAT CGN IPv4 NAT!!! Things

11 The need for IPv6 One reason: more requirement for public IP addresses The Internet is growing fast Broadband: Mobile and WiFi Internet of Things IPv6 is the only viable option Enables sustainable growth Maintains the openness of the Internet

12 Other IPv6 benefits IPv6 and privacy There are a lot of IPv6 addresses per subnet 2^64 (18,446,744,073,709,551,616 possible addresses) There s a default address randomisation known as privacy extensions that prevents tracking and port scanning of devices or sessions Provider can still attribute the address range Provides feature parity to IPv4 in investigation/legal compliance Performance No network address translation processing overhead, compared to double/triple NAT commonly seen in IPv4 networks.

over time May be discarded once everything has

13 NAT on IPv6 network Can be useful to maintain connection to old IPv4 networks Load will decrease over time May be discarded once everything has moved to IPv6 IPv6 Network IPv6 Host IPv6 Client IPv4 Host NAT64

14 IPv6 deployment challenges 1990s Protocol maturity Vendor support (Core network devices) 2000s Implementation cost Vendor support (Customer premises equipment/cpes) 2010s Application s awareness of IPv6 Business justification Technical skill

15 IPv6 deployment status Different ways to measure Number of IPv6 allocations by RIRs Number of active IPv6 BGP entries (FIB) in the routing table Comparing the numbers of ASNs advertising IPv4 vs IPv6 Percentage of devices that prefers to connect over IPv6 Percentage of users that access a network over IPv6 The volume of IPv6 requests to a CDN

16 % of IPv6 allocations by RIRs

17 # of active IPv6 BGP entries in the routing table as of 10 Nov 2016

18 Comparison of ASNs advertising IPv4 vs IPv6 as of 10 Nov 2016

19 % of devices that prefers to connect over IPv6

20 % of users that access Google over IPv6

23 Latest development

24 Conclusion IPv4 has served its purpose Time to move on Don t let NAT become a long term solution IPv6 is here Deployment growth evident from different global measurements IETF will develop networking standards that assume the use of IPv6 and do not require IPv4 The RIRs are committed to support IPv6 deployment in their respective communities

25 Priorities to consider Skills development of IPv6 skills at all levels from technical to strategic planning Transition planning national coordination of transition planning efforts Infrastructure projects incorporate IPv6 capacity into all major infrastructure Supportive government policies to be the important part of the national IPv6 innovation ISPs and Telco operators - to start planning and deploying IPv6 to last miles Downstream ASNs whose upstream provides IPv6 transit should request IPv6 to IDNIC and announce it
