NTT Communications Global IP Network (“GIN”) NTT Communications introduced next-generation IPv6 service and is striving to popularize this service on a global scale. It also served as a core network provider for World IPv6 Day (June 8, 2011), a global 24-hour test of IPv6 deployment that enabled participants to access each other's websites via IPv6 addresses.

“OCN IPv6”: IPv6 Access for Consumers

Launched in December 2005

• IPv6 Tunneling Service over IPv4 based on L2TP

• Fixed IPv6 address and non-fixed IPv6 address to be given (two /64 subnet prefixes)

• Original tunneling software provided for subscribers

OCN provides IPv6 by default for home users since Apr 2013

- IPv6 has become free of additional charge

- IPv6 Prefix is assigned automatically

- Users still need 9,000JPY (1,800,000VND) additional cost for dual stack WiFi router

Why Global IPv6 Could NOT Take Off

Additional fee needed

⇒ Reduce the usage fee and expense

Additional Customer contracts with ISP & NTT needed ⇒ Enabled IPv6 option by default

Another BOX required when the customer try to use IPv6 PPPoE


NTT East/West introduced new version of bundled CPEs (“Home Gateway”) with ISP’s IPv6 service function.

https://flets.com/news_release/info_m140304_2.html

Most existing bundled CPEs are also planned to be upgraded automatically to support IPv6 PPPoE soon.

⇒ No more additional box needed, because existing boxes are going to support IPv6

Estimated Number of OCN IPv6 Users


According to our survey,

Even though only a few hyper giants such as Google (incl. YouTube), Facebook, Akamai are IPv6 enabled, they make up most of our traffic

30-50% of traffic by volume will move to IPv6 transport immediately.

IP version transition may cause huge traffic shift between upstream providers and peers, when you have IPv6 only free peers or IPv4 only upstreams.

After You Turn IPv6 “ON” by Default

Avoid Unpredictable Traffic Shift

By unified traffic management plan for both IPv4 and IPv6 peering

Set dual stack peering as your default choice


Contribution for IPv6 Development

Turning IPv6 “On” by default may cause unintentional multi-homing

How can you setup a small network of devices which have multiple IPv6 “upstream” without NAT (as usual in IPv4)?

RFC7157 shows a possible solution

MAP-E as an IPv6 Application

MAP-E is the one of major survival technologies after IPv4 address depletion.

We assume IPv6 is the best transport for IPv4!


Our Reasons to Deploy IPv6

IPv4 has already gone.

We still need more IP addresses to provide ubiquitous Internet access for customers

To reduce future investment on Carrier Grade NAT devices
