Subject: Who controls the assignment of IP address, and under what terms?
-------------------------------------------------------------------------

This matter is an extremely important policy issue. It is our opinion that
there is a virtual policy vacuum to address this issue.

For those of you that been watching this matter, the litigation that NAC
is involved in with the plaintiff is a simple contract dispute with many
facts that are in dispute, and is irrelevant to the greater issues that
are at stake. We are not looking to have a popularity contest with NAC vs.
the plaintiff. Put us aside. This issue is much bigger then NAC.

These are complex and technical matters that should not be decided in a
court. These matters can not be decided overnight. These matters require
significant input from the network operators. ARIN should solicit the
network operators to comment (through meeting, mailing lists, RFC, etc.)
on these issues and form a consensus as to a proper set of policies to
regulate these matters.

-------------------------------------------------------------------------

The matters at stake are as follows:

1. Who is in control of IP address assignment:
Do we want the assignment and transfer of IP addresses to be determined by
ARIN or by the Judiciary (court system)?


2. Rights of the assigned:
What rights does the ISP (or other assignee) have to control the use of IP
addresses that are assigned to them by ARIN? When (and under what
limitations) can the ISP assign, and revoke IP addresses? If a customer
does not like the way an ISP assigns its IP addresses, can the customer
appeal to ARIN to intervene, or does the ISP have the final say in the
assignment of its own IP addresses?


3. Forcible transfer of IP address:
Under what circumstances should a customer have a right to have the
temporary or permanent usage of the IP addresses that are assigned to
their ISP after they have left the ISP and are no longer doing business
with them?

a. If temporary transfer is to be allowed, what limitations should be
placed on the temporary usage, or should we just let each court decide
what it thinks is fair for each case?

b. If temporary transfer is granted, does the ISP have a right to appeal?

c. What is the time period allowed for the forcible temporary transfer of
IP addresses to remain in the customer's "custody"? Is it as long as the
customer says they need the space? How long is too long?

d. Are there limitations as to the minimum quantity of the IP addresses
that can be forcibly temporarily transferred? What if a dial-up customer
has a single static IP address that they want to take with them, should
that be allowed? What about a single co-lo customer with 100 IP addresses?
Where do you draw the line? Who draws the line; the ISP, the court, ARIN,
or anyone who wants to?


4. Abuse of the usage of the IP addresses:
If an ISP is forced by ARIN or a court to allow the usage of their
assigned IP addresses, how does it handle the policing of DMCA violations,
SPAM, hacking and other abuse complaints? The ISP would have absolutely no
leverage to make the customer comply with any TOS, AUP, criminal or civil
laws. Do we think it is a good idea to have a situation where a spammer
can have their service disconnected by their ISP and the spammer can
simply go to the court to bring their IP addresses with them?


5. Liability and Cost:
If the ISP loses control of their assigned IP addresses (but they are
still assigned to the ISP), then not only can the ISP not control them,
but they would still be forced to receive and process each abuse
complaint, and still carry all legal liability for any actions taken by
the customer that is using their IP addresses. Who is going to compensate
the ISP for providing this service? Who is going to indemnify and protect
the ISP from legal action from third parties that are harmed by the
actions of the customer that is just "using" the IP addresses?

a. What happens if the ISP is sued because the customer has DMCA
violations that they refuse to correct? Who pays for the legal defense of
the ISP to explain to the plaintiff that "although the IP addresses are
assigned to the ISP, they really have no control over their own IP address
space"? Does anyone think that the company that is suing you because of
the DMCA violation understands or cares about your problems of who really
owns the IP addresses?


6. Damage to ISP's network:
If the customer makes a mistake in their routing configuration and causes
damage to the ISPs network, who is going to compensate the ISP for the
damage, and who is going to force the customer to stop causing the damage?
Is there going to be a test of routing knowledge for every customer that
wants to take their IP addresses with them?

a. What happens if an ISP has their IP addresses blackholed because a
customer is abusing (SPAM, hacking, whatever) the IP addresses that they
have taken with them? How does the ISP defend themselves? How do they get
off the RBL? How does the ISP make that customer stop?

b. What happens when the customer's routing mistakes cause a denial of
service to your other customers. How do you make them stop, how do you
order other networks not to listen to their announcements when they have
court (or ARIN) permission to announce your IP addresses?

c. Who compensates the ISP if part or their entire IP address range is
"polluted" by abuse from the customer? Will ARIN swap out the "polluted"
IP addresses with the ISP for new clean IP addresses? Will ARIN withhold
the assignment of new IP addresses because the "polluted" ones are not
being sufficiently utilized once they are returned to the ISP?


7. Damage to Internet routing:
The whole system of non-portable IP address space was done to protect the
integrity of the routing and switching of the Internet.  The current
infrastructure in use throughout the Internet is not capable of supporting
an environment where current non-portable CIDR blocks of IP address space
can be broken up and distributed as many smaller blocks or individual IP
addresses. If this were to be allowed by ARIN or ordered by the courts it
could result in a routing breakdown of the entire Internet.


For all of the above reasons I think that if these things are not decided
very carefully it will have major repercussions for the entire industry.
All network operators and other concerned parties must speak out in a very
clear voice to ARIN and to the court.
