Minutes of the Address Lifetime Expectations BOF (ALE)


Phill Gross gave an updated version of the presentation he and Dennis
Ferguson prepared for INET '93.  It included an extensive analysis and
projections of the growth of the Internet and also provided an estimate
on how efficiently IP addresses were being assigned.  The presentation
concluded with several ideas on how the address space utilization could
be improved after CIDR has been deployed:


   o Reclaiming IP network numbers which are assigned but not connected
     to the Internet.

   o Tougher address assignment policies.

   o Encouraging connected networks to renumber into a smaller portion
     of either their assigned net number (freeing up the rest of that
     net number for reassignment) or within their provider's range of
     addresses (removing the need to announce the original net number
     between providers).


The ensuing discussion was invaluable for setting the direction of the
ongoing analysis.  Some of the points that came out of that discussion
were:


   o A better feel is needed for the accuracy of the data that has been
     collected thus far.  For example, it was discovered during the
     discussion that some of the regional carriers have not been
     reporting IP address assignments back to the NIC since there was
     not any place on their templates to provide this information.

   o The IP address assignment and routing table size problems must be
     kept separate from each other at all times.  These are two
     different problems that have different factors driving them.

   o It is necessary to carefully avoid combining the data collected
     under different policy ranges into a single trend line.

   o Any graph produced that extends a trend line into the future must
     always carry the caveat that it is based on historic information.
     It cannot be predicted how future technologies or applications
     might further impact the growth of the Internet.

   o Routing table statistics should be collected from a wider variety
     of sources, since the Internet can no longer be thought of as
     having a single backbone.

   o It is necessary to evaluate and gather data about the impact (e.g.
     cost, expected gains) of any policy changes before the group makes
     specific recommendations.

   o All of the providers must buy into any recommendations made that
     affect them.  For example, if most but not all network providers
     suggest renumbering to their customers, the entire benefit could be
     lost if one ``bad guy'' provider decides to get new customers by
     allowing them to connect using their old numbers.


Frank Solensky also presented some of his more recent findings on the
effect of CIDR on the routing table size (this also appeared in Tony
Li's technical presentation on `CIDR Status' earlier in the day) and the
trend lines for the proportion of the total address space that announced
Class B and Class C net numbers consume.  He also cautioned that the
switch from announcing single Class B to multiple Class C network
numbers has occurred too recently for the trend line to be considered
reliable.

The creation of the ALE Working Group charter was deferred as an action
for the mailing list.  Discussions are now wrapping up and the charter
should be completed shortly.
