11th Masterclass - IPv6 Forum: The Technologies Behind the Smart Nation.
On 4 June 2015, more than 50 ICT professionals joined PPPO 11th Masterclass on IPv6 Forum: The Technologies Behind the Smart Nation.
The keynote speaker of the event was Dr Latiff Landid, President, International IPv6 Forum and Founding Chair, 5G World Alliance. Mr Latiff shared about The Promise of 5G. He brought the participants though the wireless generation from 1G to 5G and the transformation of non-IP to IPv6 which is the platform for global internet.
He highlighted the fundamental challenges of IPv4 32-bit size IP addresses, which is being exhausted and the many less-than-ideal work-around solutions. The real solution is to go for IPv6 with its 128-bit size IP addresses. IPv6 solution is especially important with the increasing number of devices being added from the Internet of Things (IOT) trend as it have the capacity to give each device a unique IP address.

This point was reiterated by the next speaker, Mr Champika Wijayatunga from ICANN. He pointed that to scale Internet for future demand requires a limitless supply of IP addresses and improved mobility. He told the participants that IETF have released 6loWPAN to support transmission of IPv6 packets over IEE 802.15.4 network.

Mr Lawrence E Hughes, the Co-Chair of IPv6 Forum and CTO, Sixscape Communications shared his views that IPv4 internet is broken. Network address translation (NAT) is used to glue the broken pieces. NAT is a methodology of remapping one IP address space into another by modifying network address information in Internet Protocol (IP) datagram packet headers while they are in transit across a traffic routing device. The technique was originally used for ease of rerouting traffic in IP networks without renumbering every host. It has become a popular and essential tool in conserving global address space allocations in face of IPv4 address exhaustion.
Lawrence shared that Domain Name Server (DNS) security is broken and is inadequate for mobile internet. DNS registrations can take 24 to 48 hours to propagate, which is inadequate for mobile IPv6 nodes that might change address frequently.
On the issue of username and password authentication, compromise can happen when a hacker gets access to web server and grabs a copy of the username and password database. The damage can be minimised by the use of PCF 2898, PBKDF2. The better solution is to move to Strong Client Authentication (SCA) with X.509 client certificates. Lawrence gave a glimpse of the future with a demo on how SCA works on IPv6 network that also enables true peer to peer connection without the need for NAT.

Last speaker of the day, Mr Fredrick from Beta Movement talked about what is meant by the Intention of Things and Social Objects. He shared about the case studies of Uber, Airbnb and Taskrabbit.
Wong Tack Wai, Director, Special Program Office, SiTF summed up the 11th Masterclass with a quick summary of the main points raised by the speakers and how the topics raised can help them build and operate better products. He shared with the participants on the past masterclass topics in theportal.sg that will help them go about building products better and faster. He also pointed out that PPPO has prepared a handout given to all participants on the Best Practised on IPv6 to help them get ready to embrace IPv6. Last but not least, the thanks the speakers, the participants, Progreso, IPv6 Forum and Microsoft (venue sponsor) for coming together to learn, unlearn and share in this 11th Masterclass.
