Aggregation Summary
The algorithm used in this report proposes aggregation only
when there is a precise match using the AS path, so as
to preserve traffic transit policies. Aggregation is also
proposed across non-advertised address space ('holes').

The first allocation out of 84/8 has happened. It is *now* high time to
check whether you see the pilot prefixes 84.192/16 and 84.255.248/21.
If you do not see both of these prefixes it is extremely likely that you
will have a connectivity problem very shortly. We also suggest that you
check any packet filters you may be responsible for.
Regards
Daniel Karrenberg
RIPE NCC
------
Notes:
84/8 has been allocated by the IANA on November 17th 2003,
almost 4 months ago. The fact has been announced on this list
a couple of times since.
Routing decisions are fully within the responsibility of the network
operators. The IANA and the RIRs will only announce which parts of the
address space are currently in use. They have no authority whatsoever
over routing decisions taken by you and other network operators.
More details about the pilot prefixes can be found at
http://www.ripe.net/ripe/draft-documents/deboganising-draft.html
A visibility comparison of the pilot prefixes with some production
prefixes can be found at http://www.ris.ripe.net/debogon/debogon.html
Those interested in history, see http://www.ris.ripe.net/debogon/
More information on how to do Bogon filtering efficiently and reliably
can be found at Team CYMRU: http://www.cymru.com/Bogons/index.html
Unfortunately we are not currently able to provide a host within the
pilot prefixes that can reliably answer pings, nor are we able to do
connectivity checks from there. The allocation had to happen before
we were ready with this part of the pilot prefix pilot.

Aggregation Summary
The algorithm used in this report proposes aggregation only
when there is a precise match using the AS path, so as
to preserve traffic transit policies. Aggregation is also
proposed across non-advertised address space ('holes').

Dear All,
The Inter-Domain Routing Workshop will take place at the RIPE NCC in
Amsterdam during the weekend before RIPE 48 (May 1-2, 2004). This
RIPE meeting will also be held in Amsterdam.
The goal of the workshop is to bring together a focused group of
operators, vendors, and researchers to discuss important mid- and
long-term operational problems, as well as new academic ideas, in an
OPEN forum. The wide scope for topics was intended on our part.
The organisers are:
* Intel Research
* Universität Karlsruhe Institut für Telematik
* Technische Universität München, Computer Science Department
* RIPE NCC
* Schlund+Partner AG, Karlsruhe
See URL for more information: http://www.tm.uka.de/idrws/
We are hoping that these discussions will become an invigorating and
lively affair. Please feel free to drop us a line at idrws(a)ripe.net.
Kind regards,
Matthew Williams

The algorithm used in this report proposes aggregation only
when there is a precise match using the AS path, so as
to preserve traffic transit policies. Aggregation is also
proposed across non-advertised address space ('holes').

Because they are being filtered :-) If more people filtered bogons, the
"ROI" would be even lower. Although it is clear that bogon filtering is
not a complete cure for spoofing, it does help and it also helps for
some spammers.
The only negative effect of bogon filtering is not-up-to-date filters,
which is why we have written this draft that will expand the
applicability domain of bogon route servers and other filtering schemes.

That is a misleading title.
The problem is that ISPs cannot react quickly enough
to open filters when new ranges are allocated. The proposed
solution is to provide advance notification. I suppose this
could allow ISPs to open filters before the new addresses
are actually in use officially.
However, it will also allow spammers to announce this
space and get it through bogon filters.
The real solution to this problem is to make it
possible for ISPs to closely track RIR allocations
in their filters in a semi-automated way. There may
still be a few days of delay before a new allocation
is fully routable but ISPs can compensate for that
with internal processes.
Why can't ISPs subscribe to a feed of all new
RIPE allocations in near real-time?

I haven't yet seen this message on this mailing list and I believe is
well in scope for this working group. There has been some discussion
already in the NANOG list.

"De-Bogonising New Address Blocks"
<http://www.ripe.net/ripe/draft-documents/deboganising-draft.html>
Abstract
"This document describes an improvement in the notification process
about new blocks of address space being distributed by the RIRs. It is
a draft at this stage and your comments are solicited. However to gain
experience before finalising the procedures, the RIPE NCC will shortly
start announcing the routes from 84/8 described in the document under
"84/8 Pilot"."
