[ppml] Allocation and reallocation

Greetings. After a looooong haitus I am back to managing address 
space for a company I work for. For now, at least. I am Jim Romary, 
and I used to be {host|post|news|*}master for SuperNet, a regional ISP
that got
bought at the end of 1997. Among my functions was address acquisition 
and management pre-ARIN. 

I would like to weigh in with my understanding of the two terms. I don't

feel that appeals to Merriam Webster or any other source will produce 
much clarity on this issue, BTW. As in Scrabble, we need to agree on
an authority before we start playing that game. 

My understanding has always been the one recently espoused by Cathy,
is actually less a definition than a statement of some characteristics:

Allocations can be broken up into assignments and given to customers,
but assignments can not be further delegated to other organizations, 
or customers.  

This has been even more succinctly stated by Owen, below. 

Allocations are addresses that should ALWAYS be returned by Assignees
the latter's seeking a new provider, its demise by bankruptcy, its
by another company with its own allocations, or any other event that
cause the assignee to either go off-net or be topologically different
(network-wise) to get a new provider. Theoretically, companies that need

assignments come and go, seek new providers with cheaper fares, merge,
off-shore, etc. They are and should be more mobile than Registeries. 
Allocatations to Registries can only be further assigned. Level of
and control devolves downward as the distance from uber registry, ICANN,


Allocations went to RIRs. Assignments went from the Regionals and
to their customers. Customers always returned their assignments when
sought a new Provider. I never "allocated" addresses to customers, and
this reason, we never charged for use of address space. The terms
and "ownership" were too entwined.

You came close to correct here Michael, but, you are backwards...

RIRs ALLOCATE to LIRs and both RIR and LIR can ASSIGN to end users.
