Kristina and
all,
Following are responses
below from staff where we can. I believe some of your questions highlight
the need for further study (possibly in more areas than we’ve identified in the
report, as some of your questions suggest).
Happy to try to answer
further where we can, if you have more questions. I just want to note
again too that given the short time frame to prepare the report, the breadth of
sources we were able to draw upon were necessarily limited. I really like
your idea about noting sources and including a bibliography when we prepare
issues reports in the future, and I’m going to add this as a suggestion in our
GNSO improvements process so that we capture this idea to consider in the
development of a new policy development process.
Liz

[council] Fast Flux Report - questions
All,
Here are some initial
questions/requests about the report. I will forward additional questions
soon.
Page 1: The report states that
staff "consulted other appropriate and relevant sources of information".
In the interest of transparency, I would appreciate having those sources be
identified. As a general note, it may be helpful to all readers of
the report if the issues reports included a bibliography or sources consulted
section.
LG -- staff considered
the SAC Advisory (SAC 025) and I also consulted extensively with Lyman
Chapin. We referred to the email exchanges on the SSAC list during the
period of time in which the SSAC folks were discussing fast flux and
preparing SAC 025, the presentations and transcripts from the SSAC workshops in
and
Pages 6, 14: One
interpretation of the reference to "domains in ccTLDs are targeted as well" is
that there is no "lasting value" to developing gTLD policy regarding any issue
that occurs in both gTLDs and ccTLDs. Is this interpretation
intended?
LG -- Chuck’s
comment was right. There could be a benefit to coordinating with the
ccNSO. Not making a judgment on “no lasting
value”.
Pages 6, 14: Similarly, one
interpretation of the reference to "static rules through a policy development
process might be quickly undermined by intrepid cybercriminals" is that there
can be "no lasting value" to developing gTLD policy regarding any issue that
results from or is associated with cybercriminals because they move more quickly
than the PDP and, as interpreted by one IPC member, "are smarter than we
are". Is this interpretation intended?
LG – That is why we
mention the importance of developing best practices, which then can be enhanced
and upgraded over time to keep up better with new techniques developed to
undermine existing deterrent techniques. Perhaps a policy outcome might
point to the need to adopt rigorous best practices and refresh on an ongoing
basis. But my understanding on fast flux is that these best practices do
not necessarily exist today, so the question might be how to encourage their
development in a structured and focused way, as a necessary precursor to
deciding how to encourage or require their widespread adoption. Might the
GNSO Council take on a convening role here? Or encourage or direct in some
other way? In this context, the inference of concern about “lasting value”
of imposing a specific practice is intended.
Page 8: For how long and on
what scale has proxy redirection been used to maintain high availability and
spread the network load?
LG – We need to study
this more. The key question I was raising is, “are there valid uses that
need to be considered, that could be undermined if certain deterrent steps were
imposed?” It is not clear from our cursory view how broadly this is used –
seems also unlikely that there would be need for such constant and frequent
fluxing in this context, but we couldn’t determine for sure either way.
Page 9: Did more than one
person describe evasion of "black holing" "anecdotally as a possible 'legitimate
use'" of fast flux? Any evidence or research to suggest that it actually
happens?
LG -- This is anecdotal
and may only be one entity, another potential subject of further
study.
Page 10: How likely is that
fast flux hosting "could be significantly curtailed by changes in the way in
which DNS registries and registrars currently
operate"?
LG – Would need to
study further.
Page 11: Is it technically
possible now for registries and registrars to act in two ways set forth in
report? Practically possible? If so, do they? If not, have
reasons for not doing so been provided and, if so, what are
they?
LG – Would need to
study further.
(I
have not included a scope clarification question because I understand that it
has already bee posed.)
Many thanks.
Kristina
