`Description of Working Group
`The primary purpose of the Address Lifetime Expectations Working Group is to develop an estimate
`for the remaining lifetime of the IPv4 address space based on currently known and available
`technologies. The members of the working group will consider whether more stringent address
`allocation and utilization policies might provide additional time and, if so, recommend such policies.
`The working group will also investigate whether it is worthwhile to mount a serious effort to reclaim
`addresses and/or to renumber significant portions of the Internet. It will also weigh the benefit of other
`potential options against their expected cost and notify the responsible working groups or area
`directors of those proposals the ALE group considers worthy of further attention.
`The working group will have several ongoing activities which will result in reports to the IETF
`community and the IPng Area Directors. One ongoing activity is to produce monthly predictions of
`the address space exhaustion timeframe, assessing the accuracy of these predictions and the data on
`which they are based. The group will also project the impact of various policy compliance data and
`possible policy recommendations.
`Another ongoing activity is to monitor the perceived utilization of address space and identify sources
`of poor utilization, set address utilization goals and to itemize possible policies to improve utilization.

`
`The group will also monitor the number of routes present in the Internet backbones, and identify
`sources of poor aggregation within the network, (in conjunction with the BGP Deployment Working
`Group), and make necessary recommendations to insure continued operations.
`Goals and Milestones
`Nov 93
`Coordinate with existing efforts in this area. For example, those of the IEPG and the CIDR
`Deployment Working Group. The result is an allocation of tasks agreed among the efforts.
`Done
`Make presentation to the IETF plenary on the current status of the address space utilization.
`Apr 94
`In cooperation with the BGP Deployment Working Group, produce a report on the status of
`address aggregation, including additional guidelines/strategies, if necessary.
`Produce a report on the status of address space utilization, including goals and guidelines for
`improving address space utilization. Summarize this report during the IETF plenary.
