Dear colleagues, We are pleased to announce that we have implemented RIPE policy proposal 2017-02 "Regular abuse-c Validation". This policy gives the RIPE NCC a mandate to regularly validate "abuse-mailbox:" information and to follow up in cases where the attribute is deemed to be incorrect. As part of the implementation, we carried out an initial validation of all "abuse-mailbox:" attributes in the RIPE Database that reference Internet number resources. Of around 77,000 email addresses, ~5,500 were marked as invalid and we followed up to ensure they contained a working email. The archived policy proposal can be found at: https://www.ripe.net/participate/policies/proposals/2017-02 <https://www.ripe.net/participate/policies/proposals/2017-02> The RIPE Document, "Abuse Contact Management in the RIPE Database" is available at: https://www.ripe.net/publications/docs/ripe-705 <https://www.ripe.net/publications/docs/ripe-705> We would like to thank everyone for their support as we performed our validation. The feedback you shared with us on our process and tools was especially helpful. Kind regards, Stefania Fokaeos RIPE NCC Registration Services
