Nanog hosted a panel discussion this morning which included a number of
different aspects of the transfer policy.  I'd encourage people to
review the video and/or transcript once it is published.


One thing area of discussion that I thought was interesting and somewhat
different than I expected is the following and that probably needs some

Someone asked what happens if...

Vendor A sells a /16 to Vendor B.  Vendor B can justify a /20 under
current policy.  ARIN's response (channeling John Curran's response to
this question) to this transfer would be to update the WHOIS to reflect
that Vendor B now has a /20. 

This leaves a very uncomfortable situation of what happens to the rest
of the /16. 
Does the remainder of the /16 become "unallocated" from a WHOIS
perspective or does Vendor A still have some claim on it (e.g. the
original /16 record remains)? 
Later can Vendor B come back to ARIN and say now I can justify a /18,
please update my WHOIS record?
