Dear Colleagues,
The RIPE NCC received the IPv6 address range 2001:4C00::/23
from the IANA in December 2004.
You may wish to adjust any filters you have in place accordingly.
More information on the IP space administered by the RIPE NCC
can be found on our web site at:

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').

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').

Interestingly enough what Covad appears to be saying is:
If we had a way to announce two things
1 - here are the advertisements for covering aggregates for Covad
AND
2 - do not believe any more specifics for these address blocks, as they are
NOT part of Covad's routing policy for these prefixes
then we would not be seeing this unfortunate case of unauthorized route
leakage being resolved in a way that seems to have unfortunate bgp
implications in terms of more specifics appearing.
So its an interesting question. How could Covad achieve a routing policy
announcement of the form as stated in 2 above?
regards,
Geoff
