The document discusses IPv6 readiness in Sri Lanka. It notes that Sri Lanka has 10 ISPs including Sri Lanka Telecom and Dialog. An IPv6 working group was established in 2011 to develop a national IPv6 roadmap and address assignment policy. The working group focuses on areas like infrastructure readiness, awareness, and managing the transition. Sri Lanka Telecom's core network supports IPv6 and it provides IPv6 addresses to customers and other ISPs, but network traffic over IPv6 is still low. Customer devices often only support IPv4 by default and there is a lack of awareness. Future plans include issuing dual-stack CPEs and providing static IPv6 to mobile networks.

3. IPv6 Working Group
Sri Lanka Computer Emergency Readiness Team | Coordination Centre
Ø Established in 2011 under the Telecommunications
Regulatory Commission of Sri Lanka
Ø Objectives:
Identify WHAT should be done WHEN in order to prepare the
Nation for IPv6 adoption & penetration
Select specific targets to achieve in order to develop IPv6
penetration up to total inclusion

3.Infrastructure readiness
4.HR development
5.Awareness & Publicity
6.Managing the Transition Period
7.Implementation

5. Drafted Documents
Sri Lanka Computer Emergency Readiness Team | Coordination Centre
Ø National IPv6 roadmap
Ø IPv6 address assignment policy

6. IPv6 allocation and BGP advertisement
Sri Lanka Computer Emergency Readiness Team | Coordination Centre
Sri Lanka Telecom
Ø Core network is ready for IPv6
Ø All v6 prefixes are advertised
Ø All uplinks are dual stack
Ø Core network is ready for IPv6
Ø Providing IPv6 addresses to customers and advertising them
Ø Customer IPv6 blocks (LEARN, LANKACOM) are advertised
Dialog

7. Network traffic over IPv6
Sri Lanka Computer Emergency Readiness Team | Coordination Centre
Sri Lanka Telecom
Ø Have not measured yet.
Ø It will be low as most of the connections are still v4
Ø 5 Gbps on peak
Dialog

8. End user readiness over IPv6
Sri Lanka Computer Emergency Readiness Team | Coordination Centre
Sri Lanka Telecom
ØNo demand from customers
ØProviding v6 connections to other ISPs and Enterprise customers
ØStill not providing for retail customers
ØProviding dual stack to customers (4G –Dual Stack, 3G-single stack)
ØMost of the terminals are IPv6 ready
ØReady to provide IPv6 to fixed Broadband and Enterprise users
ØLess interest among Enterprise sector as they think that NAT is a
security mechanism
Dialog

9. DNS query from ccTLD over IPv6
Sri Lanka Computer Emergency Readiness Team | Coordination Centre
Sri Lanka Telecom
Ø All DNS servers support dual stack
ØPlanning to dual stack all of the DNS servers
Dialog

10. Web services availability over IPv6
Sri Lanka Computer Emergency Readiness Team | Coordination Centre
Sri Lanka Telecom
Ø www.slt.lk is dual stacked
Ø Web servers support dual stack
Ø NAT 64, DNS 64 is ready
Ø Currently www.dialog.lk is dual stacked
ØCustomers are bit reluctant to have IPv6 due to potential security
issues
Dialog

11. Security
Sri Lanka Computer Emergency Readiness Team | Coordination Centre
Sri Lanka Telecom
Ø Signature based security issues (AV, IPS/IDS etc) still not
issued for v6
Ø LTE CPEs cannot be accessed via IPv6
Ø End user security is handled by end user OS,AV, FW etc.
Dialog

12. Current issues
Sri Lanka Computer Emergency Readiness Team | Coordination Centre
Sri Lanka Telecom
Ø Default setting of CPEs are IPv4 only. Customer has to select
IPv6.
Ø CPE readiness and lack of customer awareness
Dialog

13. Future plans
Sri Lanka Computer Emergency Readiness Team | Coordination Centre
Sri Lanka Telecom
Ø Issuing CPEs with dual stack support by default
Ø Working on to provide static IPv6 to mobile sector
Ø Can provide IPv6 for Moblile phones, 3G dongles. But devices are
not ready
Dialog
