...these new devices will still not be able to connect with other equipment on the internet that is only using IPv4. That is unless a process called dual-stacking is used.
This process allows IPv4 and IPv6 to run side by side, communicating either individually, or using a hybrid of the two. Dual-stacking acts as a working stopgap but is not ideal because it comes with added cost and technological complexity.
Complete IPv6 deployment needs to take place across the board to avoid a two-tiered internet, one on IPv4 and the other on IPv6. Countries such as Russia, South Korea, Kenya and even Nepal either have or will have 4G LTE mobile internet networks by the end of 2011 but the UK will probably have to wait until 2014 before its inhabitants can access such networks.
Some have complained that the UK has fallen behind on 4G LTE — Norway and Sweden received super-fast 4G LTE mobile broadband services in 2009 — but there has been relatively little acknowledgement of the situation on IPv4 exhaustion and IPv6 deployment.
Russia is also one of the leading countries in IPv6 deployment, along with France, Ukraine, China, US, Poland, Sweden, Canada, The Netherlands and Japan which all make up the top 10 countries by deployment levels. It would seem that just like with 4G LTE adoption, the UK is just not keeping pace.
Growth in smartphone ownership
Smartphone and tablet ownership is on the rise and there has been a growing realisation of the role mobile can play in meeting the government's national broadband commitment by 2015.
Any significant delay in 4G LTE puts this goal at risk and will further weaken competition and user experience to the detriment of UK consumers.
Similarly, any delay in IPv6 deployment could prevent long-term internet growth and global communication, as new devices that are IPv6-only will not be able to communicate with the IPv4-only networks.
