Why IPv6?


In The Beginning...

Internet of Things


Everything over

IP


Only 2-3 Billion People Are Online –

What About The Other 5 Billion?

And IPv4 only has 4.3 billion addresses!


How IP Address Allocation Works

Regional Internet Registries (RIRs)

Internet Service Providers (ISPs)

You


Global IPv4 Disparity !


As of Feb 1, 2011...


Internet Service Providers (ISPs)

You

All Out!

It's Even Worse…


All Out!

The Problem?

SIP NAT


Challenges with CGN/LSN

•  Increased latency •  Impact to communication, gaming, video streaming

•  Challenges with logging

•  Difficulty finding data for law enforcement agencies •  Geoff Huston (APNIC) on CGN and law enforcement •  http://www.potaroo.net/presentations/2014-03-12-cgns.pdf

•  Added network complexity

•  RFC 7021, Assessing the Impact of Carrier-Grade NAT on Network Applications

•  https://tools.ietf.org/html/rfc7021


And then there is...


IPv6

2001:db8:34a5:23::9009:1234

But… how do you enter IPv6 here?


Also, the simple picture…

Next Steps


Next Steps

1.  Learn about IPV6!

2.  Obtain IPv6 connectivity

3.  Inventory your existing equipment and applications

4.  Start specifying IPv6 as a requirement for new purchases §  RIPE-554: http://www.ripe.net/ripe/docs/ripe-554

5.  Set up a test lab

6.  Join the SIP Forum IPv6 Task Group mailing list
