Today, we are happy to announce that all address space that was historically transferred to the RIPE NCC from other Regional Internet Registries (RIRs) is also eligible.<br><br>These ranges are so called "minority" address space, meaning that the full /8 block is managed by one of the four other RIRs, but a subset is managed by the RIPE NCC. LIRs who hold address space in these minority ranges will automatically have those resources added to their certificate, if they already have one. Starting today, they can create Route Origin Authorisations (ROAs) for the BGP announcements that they make with these prefixes.<br><br>Resource Certification (RPKI) is a free service offered by all RIRs to offer BGP Origin Validation. It allows operators to request a digital certificate containing their Internet number resources and make cryptographically verifiable statements about their intended BGP announcements. These ROAs allow other network operators to make reliable routing decisions. In the RIPE NCC service region, more than 1,600 LIRs have requested a resource certificate and created ROAs for over six /8s worth of address space.<br><br>To read more about this service, please visit:<br><a href="http://ripe.net/certification">http://ripe.net/certification</a><br><br>If you have any questions, please do not hesitate to contact us at <<a href="mailto:certification@ripe.net">certification@ripe.net</a>><br><br>Kind regards,<div><br></div><div>Alex Band</div><div>Product Manager</div><div>RIPE NCC</div></body></html>
