Yes, it was good when we (means all ISP) had many IPv4 addresses.<br />
<br />
In several month PI space will be unavailable and for more efficient using IPv4<br />
big ISP will allow use PA space for using to smaller ISP.<br />

<br />
It is not problem. Each customer has contract and on termination the contract all<br />
Assigned PA space client return back.<br />

Well, the point of "PA" is the "A" for "Aggregation". It can be announced<br />
(as a hole) from their own AS, but MUST NOT be taken away from the original<br />
provider. If the customer terminates the contract with the ISP who has<br />
been allocated the PA block from RIPE, the PA space MUST be returned.<br />
<br />
Just because it (sometimes) works technically doesn't mean it's intended<br />
to be used that way, or will not cause major problems later on - as you<br />
have discovered.<br />
