The March of the IPv6 Internet

gunter_vandeveldeBy Gunter Van de Velde, Sr Technical Leader, NOSTG Engineering

It has been a year since the World IPv6 Launch and in that year the global usage of IPv6 has more than doubled. Where traditionally it is believed that there is no IPv6 traffic on the Internet is now shown differently! The reality of real existing user traffic demonstrates the progress of the next generation of the Internet. During the World IPv6 Launch a year ago there was about 0.64% of Internet traffic carried over IPv6, while right now about 1.35% of the Internet traffic is carried over IPv6. That is nearly double and experts believe exponential growth is expected over the next couple of years.

Another data-point is the readiness of the service providers regarding IPv6. On the Internet there are about 44,470 Autonomous networks announcing one or more IPv6 prefixes into the global routing system. A year ago only about 13.7% of them were announcing IPv6 prefixes. That number increased to 16.1% resulting in 7.168 networks out of the 44.470 that are announcing IPv6 prefixes right now.

Ignore the Mouse – Get Your IPv6 Learn On at Cisco Live Orlando 2013

simloBy Steve Simlo, IPv6 Product Manager, Cisco Network Operating Systems Technology Group

As IPv6 gains more and more ground within the Internet we are starting to see recognition amongst the wider community that technologies such as Carrier Grade NAT (CGNAT) have some significant drawbacks from a service and scalability standpoint. Some of the issues were recently highlighted by a major carrier which actually issued a public “opt out” option to their customers if needed.

However, there are some applications such as online gaming, VPN access, FTP service, surveillance cameras, etc., that may not work when broadband service is provided via a CGN. For our customers utilizing these types of applications, we provide the ability to “opt out” of CGN Read More »

Cisco Fellow Mark Townsley: A Better Way to Deploy IPv6

We first talked about the Mapping of Address and Port (MAP) method to handle IPv4 exhaust and the transition to IPv6 last week. MAP is based on two IETF drafts currently in the process of standardization in draft-ietf-softwire-map (MAP-E) and draft-ietf-softwire-map-t (MAP-T). The real advantage with MAP is that it’s stateless and doesn’t require additional hardware as traffic grows.   Read More »

A MAP to Easier, More Scalable IPv6 Deployments

There are a number of ways to deal with IPv4 exhaust and  IPv6 transition, including Carrier Grade NAT and stateful Dual Stack Lite. Cisco has added another method called Mapping of Address and Port (MAP) based on two IETF drafts currently in the process of standardization in draft-ietf-softwire-map (MAP-E) and draft-ietf-softwire-map-t (MAP-T). The real advantage with MAP is that it’s stateless and doesn’t require additional hardware as traffic grows. In fact, the MAP implementation on the Cisco ASR 1000 or ASR 9000 is just a software feature that can be enabled as needed. Read More »

End of the World Revisited: No More IPs!

We’ve posted this before, but in honor of the end of the Mayan calendar and the destruction of the world which was forecast for today we’re posting it again. In our mind, not having any more IP addresses would be a terrible event -  if you’re going to build the Internet of Everything you need a lot of IP addresses! Read More »
