2. Background
• Internet Protocol (IP) is the primary protocol in the Internet
layer of the Open Systems Interconnection (OSI)
networking model
• IP’s job is to deliver packets from a source computer to a
destination computer
• As of May 2015, about 97% of web traffic uses IPv4
• IPv6 is intended to eventually replace IPv4

3. Why IPv6?
• IPv4 was developed in the 1980’s when the Internet was in
its early stage
• IPv4 does not support near enough addresses to connect
all the world’s devices
– IPv4 only supports 4.3 billion addresses
• Worlds population as of today is 7.3 billion
– UN estimates to increase to 11.2 billion by year 2100
• Mobile phones explosion around the world
– 4.01 billion in 2013
– 4.43 billion in 2015
– 5.07 billion by 2019

5. How IPv6 deployment is going?
This varies around the world in terms of…
– Address deployment
• Have the networks got addresses?
– Routing deployment
• Do they show in the routing table?
– Content readiness on IPv6
– User capability
• Can end-users use IPv6 and access content?

22. IPv6 in mobile networks
• 3G+ and 4G (LTE, TD-LTE): Services on voice, messaging
and data are converging on IP-based services
• Rapidly increasing global 3G+ and 4G deployment
– Some mobile network operators already deployed IPv6

24. Observation
• IPv6 deployment is increasing steadily
– But varies among regions, economies, and individual ASNs
– Not happening simultaneously
– Some economies and ASNs have been very active in terms of IPv6
deployment
• Particularly some mobile network operators and cable TV operators
• Once they enable IPv6 in their network and handsets, their end user
readiness grows VERY rapidly
• Where are you now in terms of IPv6 deployment?
