<p>Hello</p>
<p>I think this is something unnecessary.<br>
It is good that ARIN is careful about making sure reissued space
is not routed or present in blocklists before assigning it to a
new holder, but should not be obligatory, specially in times of
IPv4 exhaustion.<br>
Between assigning something to an organization that requires it to
exist in the Internet and not assigning at all, some may choose to
receive the space and deal with the issue afterwards.</p>
<p>The reason a block may be in a blacklist is out of the control of
ARIN and it should reduce the capacity to do its duties which is
assign space to organizations because of a 3rd party problem that
it is not their duty to resolve. Therefore leave it without it and
perhaps at maximum have a minimum time hold time.</p>

<p>PS: It seems to be a hell the existence of these type of
blacklists that don't look to have any criteria to add or removed
addresses, ending up some space to stay there indefinitively.
There may be blacklists to be used for blackhole or similar
proposes, but be restricted to a DDoS mitigation scenario, not to
have addresses permanently banned.<br>
If there are serious issues regarding IP space being used for
criminal activities this should be seriously treated via the
appropriate abuse contacts and at the worst case scenario be
brought to the attention to the RIR and be considered IP space
missusage. I don't think anyone can defend in such cases that the
RIR should not have anything to do with the way that IP space is
used.<br>
<br>
Last and not less important there are blacklist that are targeted
to be used only for spam combat and in such cases there is
absolutely no issues with having certain IP space present there. I
have seen cases where people confuse things and believe those
lists are to be applied for any type of Internet traffic.</p>

<p class="MsoNormal">It has been brought to the attention of the
Policy Experience Working Group that in rare circumstances it
is possible that Internet resources re-issued from revoked RSA
space may have been on a block list or currently routed. The
ARIN staff is very careful to make sure that any reissued
space is not routed so as to cause some unaware 3rd party
problems with their business as well as the new holder. ARIN
also aims to avoid providing space that appears on block lists
and is diligent in researching these issues.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As a community, would you like to see
clarification in section 4.1.8, stating something like: Space
revoked per the RSA has had no substantial routing table usage
since revocation and has met a six month hold time?<o:p></o:p></p>
