Policy Proposal 2003-13: Six Month Supply of IP Addresses

After a subscriber has been a member of ARIN for one year they may
choose to request a 6 month supply of IP addresses.

###################################################

Discussion of the proposal by Michael Dillon:

This is basically intended to reduce some of the administrative burden at
both the subscriber/member and at ARIN. It means that members can choose
to have, on average, two interactions with ARIN per year rather than 4.
There is some benefit to the community in forcing newcomers to interact
every 3 months because of the need to learn and gain experience, but
beyond the first year, we should let people have more flexibility.

This will also allow larger members with more bureaucratic internal
processes to avoid internal address shortage crises. I have mentioned this
on the ppml list before in the following paragraph:

   Here's what I mean. If your goal was to maximize the efficiency
   of address assignment, then you would eventually reach an upper
   limit for every netblock beyond which you can't improve efficiency.
   I'm assuming that is greater than 80% utilization. That means that
   when you reach 80% on your last netblock, you have already used
   up all possible addresses on previous netblocks so that you only
   have the last 20% of the most recent netblock to allocate. In
   fact, you probably have less than 20% because it is not possible
   to assign IPv4 addresses to 100% efficiency. Assuming that the
   allocation is based on 3 months of usage, i.e. 13 weeks, this
   means that you have no more than 2.6 weeks supply of addresses
   left when you submit your ARIN application. The .6 weeks will
   be used up by ARIN's 2-3 business days of turnaround time so
   you will only have 2 weeks to get these new addresses into your
   systems. The people who do this work also do other planned and
   break-fix operational work so they can't be expected to just
   drop everything and handle these new IP addresses every time.

Timetable for implementation

I suggest that this proposal should be implemented within 30 days of a
decision by a members meeting.
