RIPE NCC

• Service region: Europe, Middle East and parts of Central Asia

• Supports coordination of Internet operations

• Not-for-profit membership organisation

• Over 7,000 members

• Neutral, impartial, open and transparent

• RIPE: self regulated, open to everyone

Activities

• Distributing and managing number resources

• Routing Registry

• Statistics and measurements

• Education

• K-root

• ENUM root zone

The Solution

Internet Protocol Version 6 (IPv6)

• Uses 128 bit address space

• Allows for far more than 4 billion addresses

• Designed in 1992

• Not backwards compatible with IPv4

Challenges

20

• Technology has to be ready

• Requires training

• Requires a different view on the product

The Alternatives

Network Address Translation

• Extends the capacity of the IPv4 address space by sharing an IPv4 address between clients

• Fairly common technology, used everywhere

• Breaks the end to end connectivity model

• It limits development!

• You are probably going to need it in some form

IPv6 RIPEness

• Rating system designed to monitor progress in the deployment of IPv6

• Four “stars” to earn, based on the level of deployment:– First star for getting an IPv6 allocation

– Subsequent stars awarded for visibility, route objects and reverse DNS

• Only lists RIPE NCC members
