Dear colleagues,
I am happy to announce that the following Independent Internet number resources are now eligible for Resource Certification (RPKI):
- IPv4 and IPv6 Provider Independent, listed in your LIR Portal account as "INFRA"
- IPv4 and IPv6 Anycast, listed in your LIR Portal account as "INFRA"
You can now create Route Origin Authorisations (ROAs) for the BGP announcements with this address space. Pay careful attention that *all* BGP announcements with your prefixes are RPKI VALID. You can verify this in the "My ROA Specifications" tab of the Resource Certification portal, under "Current BGP announcements".
Please visit http://ripe.net/certification for more information.

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').
