12 February 2004Phnom Penh, Cambodia

Paul Wilson, APNIC

Overview – Part 2

• Allocation statistics – Asia Pacific Internet Resource statistics– Global Internet Resource statistics– IPv4 lifetime expectation

• More on Addressing policy– How to participate in open policy

processes

APNIC Internet Resource Allocation

Resource Allocation Statistics

• IP addresses mirror Internet growth– Represent deployed infrastructure– Distributed in consistent fashion– APNIC can provide objective, factual info

• Analysis of trends…– Allocation patterns per country over time– Comparison with other regions– Correlation of IP addresses with...

• Population, GDP, etc

IPv4 Address Lifetime Expectancy

- Are we running out of IPv4 addresses?

Research activityconducted by Geoff Huston

and supported by APNIC

Are We Running Out of IPv4?

• Recent media reports claiming we are running out of IP addresses– Some claim we’ve already run out in some parts

of the world• But what are the facts?

– Is the IPv4 sky falling?• Geoff Huston, chief scientist in the Internet

area at Telstra, has studied the IPv4 consumption rates

http://www.potaroo.net/ispcolumn/2003-07-v4-address-lifetime/ale.pdf

Data Analysed

• Three views to make forward projections:– The rate at which IPv4 number blocks

are passed from IANA to the RIRs– The rate at which RIRs undertake

assignments of IPv4 address blocks to LIRs and end users

– The growth of the number of announced addresses in the BGP routing table

Observations

• Extrapolation of current allocation practices and BGP-based demand model

• Derived from 2000-2003 data• Considering

– IANA/RIR unallocated pool– Total address space including allocated but

unannounced• Assuming exponential growth

– Address space lasts until 2025, or up to 2029• Assuming linear growth

– Address space lasts until 2037 - 2047

Issues

• This is just a model - reality will be different!• Will the BGP routing table continue to

reflect allocation rates? • Is the model of the unadvertised pools and

RIR holding pools appropriate?• Externalities…

– What are the underlying growth drivers (applications) and how are these best modeled?

– What forms of disruptive events would alter this model, and to what extent?

– Should address management policies change as a result of these results?

the Policy Development Process

What is the APNIC community?

ISP Associations

Policy Development

• Industry self-regulatory processes– Open to all interested parties– Facilitated by RIR staff and volunteers

• Policy implementation– RIR processes– ISPs and other affected parties

Participation in policy processes

• Why should I bother?– Responsibility as an APNIC member

• To be aware of the current policies for managing address space allocated to you

– Business reasons• Policies affect your business operating

environment and are constantly changing• Ensure your ‘needs’ are met

– Educational• Learn and share experiences• Stay abreast with ‘best practices’ in the

Internet
