 I received an e-mail this morning from a company claiming that IP Space can now be leased.

Was just wondering if this was legal.

Enrique -

   If by "legal", you mean "in compliance with the community number resource
   management policy in this region", then perhaps I can provide some insight.

   Internet service providers routinely provide IP address assignments as part
   of their Internet services bundle, and those assignments are not permanent
   in nature but only for the duration of the service agreement.   Many would
   consider such assignments to be "leased IP address space".

   Organizations receiving IP address space (as the recipient of a transfer or
   via allocations of IP address space from the free pool) as an ISP must meet
   the LIR definition (per NRPM 2.4) and that means "primarily assigning address
   space to the users of the network services that it provides."   End-users
   receiving transfers or assignments of IP address space from the free pool
   must meet the End-user definition (per NRPM 2.6) during their request which
   requires they be receiving space to be used "exclusively for use in its
   operational networks."

   Ergo, the "leasing" of recently received space could reasonably raise
   concern about whether the request to ARIN for that space was made with
   full sincerity, and organizations would be advised not to request to receive
   IP address from the free pool or as the recipient of a transfer if their intent
   is to "lease" the space rather then use it for their network service customers
   (if an ISP) or use it for their own network (if they applied as an end-user.)

   There has been no policy development specifically regarding leasing as an
   appropriate/inappropriate use of held IP address space, so ARIN does not
   have a position either way (aside from the case above of insuring that
   requests to receive additional address space are made in good faith based
   on existing definitions of usage.)  Obviously, individual  Internet service
   providers may have their own views on handling of "leased" address space,
   depending on any number of factors including registrant and block size.

   I hope this helps somewhat in understanding the situation, recognizing
   that it is not likely to be as complete an answer as you would have liked.
