Maybe it is helpful if I explain the difference between
allocation and assignment.
An allocation is a range of addresses that can be further
subdivided. It is given to both customers to address their
networks and used to address equipment in your own network.
An assignment is a range of addresses actually *in use* on a
specific network. Assignments must only be made for specific,
documented purposes and may not be sub-assigned.
There is no such thing as an 'Allocated Portable assignment' as
mentioned above. There are both assignments and allocations as
Database entries in the whois database - but they are separate
entities.
Most allocations will be marked 'Allocated Portable'. That is,
the custodian has a range of addresses that they can use to
*assign* to their customers and to themselves for their network infrastructure.
Those customers *must* have connectivity through the ISP that has
the range of addresses (allocation). The idea is that the ISP
aggregates the allocated range into a single prefix announcement, usually
a /20 (which is the minimum allocation size). The 'portable' tag only applies
to the /20 range as a whole. It means the custodian of the range
(say your company) can change upstream provider without
renumbering.
Any assignments customers receive will be marked in the whois
database as 'assigned non-portable'. this means that they have
received assignments from your range (allocation) to be used on an actual
network. They cannot leave you, choose another provider, and take
the addresses with them. They are *not* portable. You should enter
into agreements with your customers which specify that they addresses
are not portable, should they cancel their service with you.
This whole idea is in place to support the hierarchical aggregation
of routing information. This is to date, the only effective way to
make the Internet scale, and is critical. It is known as CIDR (classless
inter-domain routing).

No - you should *definately* be assigning it to your customers. You can
also assign it to your sister companies but only *IF* they obtain
Internet connectivity from you.

Whether you are commerical or not has no bearing on where the addresses
are assigned. The important thing to remember is that addresses *must*
only be assigned to entities that are receiving Internet connectivity
from you.
Does that help? Please dont hesitate to contact me or the helpdesk
if any of this is not clear.
Kind regards,
Anne
