No.

Policies do not enforce anything. Policies are like laws. They are
just words on paper. Enforcement has to come from somewhere=20
else.

If you read RIPE policies carefully, you will see that you do not have
to have a technical requirement today for every address that you
receive from RIPE. If RIPE is willing to give addresses to some=20
organizations which will not be used for many months, or years,
then it is difficult to force any organization to return addresses=20
when they experience a temporary downturn. Also, remember that most
RIPE members will reserve unused addresses for several months after
disconnecting a customer, before they assign those to other customers.

In the case of a dispute between RIPE and a member organization,
you cannot expect quick results. There will almost always be a
language barrier between RIPE and the member organization. The
multilingual hostmasters are probably not the right people to
be in the middle of a dispute. There are subtle difference in=20
translating a lot of the terminology that we use, for instance
assign and allocate have almost identical meanings in English,
so I don't expect translated terms to make any sense outside of
the RIPE context.

Let's face it, we are running out of IPv4 and the special efforts
that RIPE has made in the past year or so, has only caused this
runout date to become sooner for all but the smallest organizations.
IPv6 is the only way out of this mess. Attempting to enforce some=20
sort of efficient-use policy for IPv4 is wasted effort.

顧客を失った企業から"ポリシー"として不要なIPアドレスの返却を"強制"できないか、
という質問に対する返答。端的に言うと、ポリシーで強制はできません、という話。

どのRIRでも既存の巨大Allocationを受けた企業から回収する方法に苦慮している。
どんなインセンティブを与えるか・・・
今まで検討された案は大部分が、先行者利益をかなり認める形でなかなか合意が得られない。
難しい。
