[arin-ppml] About needs basis in 8.3 transfers

We had a discussion today at NANOG in the ARIN PPC about needs-basis in 8.3 transfers.

I'd like to state the following, and then let's see where the discussion takes us:

My team runs an AS. And yep, we're a pretty big company.  We rely on IPv4 today for most of our numbering, and will continue to do so for the next couple of years.[1]  In the coming year, when we can't get space from ARIN or other RIRs, we have to turn to the market for our IP address needs.   We may choose to buy more than a 2 year supply, because it may make business sense for us to do so.   ARIN policy, however, only allows us to take the IP addresses we buy and transfer the portion which represents a 2 year need.   The rest will remain in the name of whoever sold the IP addresses to us.

Why is this result good for the operator community?  Wouldn't it be better if ARIN rules allowed us to transfer into our name all the IP addresses which we now own?


[1] We're working on increasing IPv6 presence in our network and our products, but large corporations move slowly ;)
