CURRENT_MEETING_REPORT_
Reported by Frank Solensky/FTP Software
Minutes of the Address Lifetime Expectations Working Group (ALE)
Tony Li and Frank Solensky presented their analyses of the growth rates
of the InterNIC's assigned and allocated address space. While the
aggregate growth rate in the number assignments haven't changed the
depletion dates significantly on the linear model, a substantial
increase in the number of allocated Class Cs during March brought the
estimated depletion dates in by several years on the logistic model. A
lively discussion on what these numbers represent followed and a
recommendation was subsequently sent to the IEPG list that preparations
be made so that IANA can start allocating portions of the Class A number
space.
Frank also presented some preliminary results of the IPv4-ALE address
survey sent out a few weeks earlier (results given below), designed to
ascertain how efficiently number space within network numbers was being
utilized and how much could be reclaimed voluntarily. A lively
discussion on the feasibility and methodology for reclaiming unused
number space followed. The chairs reminded the working group that the
charter described the group's function as more of an advisory than a
policy making position and agreed to gather more information about the
unreserved Class A network numbers which are not currently announced in
the routing tables.
