[menog] Microsoft offered $7.5M for Nortel's IPv4

ARIN rules could be difficult to impose on pre-IANA blocks; Nortel had IP addresses before IANA and ARIN came into existence, so this may go to court if ARIN wants to block it. But Microsoft could have a right to ask for these addresses as they are into cloud services which needs a lot of IPs, so ARIN may agree. And IANA records shows Bell Northern Research, later part of Nortel, was assigned its own /8 block in January 1991.

Supply and demand rules mean that IPv4 address costs will only go up, so Microsoft likely got a really good deal.  And Asia-Pacific v4 addresses, from APNIC, are drying up within a month (by April !), so the v4 shortage situation will be worse. 

Even if one has enough v4 addresses , we will reach a point sometime within the next 2 years when we will need v6 access to connect to global IP services that are starved of v4.

So, If I may ask, what is ARIN's current position and what can be ARIN's possible re-action(general speaking)?

  Nortel may or may not be bound by ARIN's rules, but, ARIN is the registry and
  as such, if you want a transfer recognized in the registry, you will need to conduct
  the transfer according to the policies present in the registry.

  Outside of the registry, anyone who wants to can run their own internet using
  whatever rules they choose to.

  Of course, what happens when one attempts to connect one of these other
  private internets to the IANA/RIR/RFC cooperating internet is rather vague
  and undefined and I leave speculations about such as an exercise for the
