Subject: Re: [sig-policy] SIG Policy Proposal 'Preventing the routing of 'dark' address space
Good Morning Mr. Okutani and APNIC Secretariat,
Thank you for reading the proposal and your associated questions on
the sig-policy proposal
'Preventing the routing of 'dark' address space'. I have responded in
line using the tag [Response]
below for each one of your concerns. I have also included an example.

[Response] - Yes, I am essentially proposing the first at ALL levels of
routing. I do understand that
this would be larger than APNIC's reach and would need to be applied
Internet wide. I am proposing
this be applied to ALL who receive their IP address allocations from
APNIC directly or indirectly.
Included within the proposal are the Tier 1 backbone providers as well
as individual ISP. I have
attached an example of what I am proposing below.
However I do believe that it would be within APNIC's address policy
because if APNIC
was able to initially assign the IP address space to begin with, APNIC
should be able to
remove the address space it originally assigned.

[Response] - The proposal I have submitted proposes the loss of IP
address space at the point
where routing "drops off" in to "dark space". Let me provide an actual
traceroute. As of a couple
of minutes ago, node 19 222.233.52.27 was still active. That is 6 days
after this traceroute was
taken.
I received an "Failure to Delivery Notice" for an email that I had not
sent, that was a item of SPAM
that directed the reader to the IP address 222.233.52.27.

=================
You will notice that starting with node 15 the address space is un
allocated. Thus the last
legal space rests with node 14 which now has a problem with their
routing tables.
I am proposing that notification be given (in this case) to
12.119.138.38 "holder" to repair their
routing tables. If not acted upon within a reasonable period of time
and possibly a number
of similiar instances, then the "holder" of the 12.0.0.0 -
12.255.255.255 address space loose
their IP assignment. Yes, I am proposing that in this example, the
POSSIBLY that after 7 days of
inaction after being notified, AT&T WorldNet Services would loose their
IP allocation,
if they received their IP allocation from APNIC. In this case they did
not, and that is why I
do understand that this would need to be adopted Internet wide. I am
also interested to see how
long 222.233.52.27 remains active after this email is sent.
How might this work. There are a number of SPAM services that receive
spam from their users.
They parse the spam extracting the possible originating IP addresses of
the spam, AND the IP addresses
the SPAM is directing the reader to. I am proposing to take the
extracted address the SPAM reader
is sent to, traceroute it, determine the last legal IP address on the
route and send an automated
notification to that service provider, whom ever that may be.
With respect to the question of "removal" of IP address space, I would
propose the logical loss
of routing to the IP address space in question.
I hope I have answered your questions.
Thank you very much,
Gordon
