Introduction There are circumstances in RPKI operations where a resource holder's parent may not be able to, or may not choose to, facilitate full and proper registration of the holder's data. As in real life, the holder may form a relationship to their grandparent who is willing to aid the grandchild. This document describes simple procedures for doing so. One example would be when provider A allowed a child, C, to move to other provider(s) and keep their address space, either temporarily or permanently, and C's child, G, wished to stay with provider A. Other examples occur in administrative hierarchies, such as large organizations or military and other government hierarchies, when A's child C wishes to manage their own data but does not wish the technical or administrative burden of managing their children's, Gs', data. 2. Suggested Reading It is assumed that the reader understands the RPKI, see [RFC6480], ROAs, see [RFC6482], BGPSEC Router Certificates, see [I-D.ietf-sidr-bgpsec-pki-profiles], and the operational guidance for origin validation, [I-D.ietf-sidr-origin-ops]. 3. What to Do A hypothetical example might be that A has the rights to 10.0.0.0/8, has delegated 10.42.0.0/16 to their child C, who delegated 10.42.2.0/23 to their child G. C has changed providers and kept, with A's consent, 10.42.0.0/16, but G wishes to stay with A and keep 10.42.2.0/23. Perhaps there are also AS resources involved, and G wishes to issue Router Certificates for their AS(s). Managing RPKI data in such relationships is simple, but should be done carefully. First, using whatever administrative and/or contractual procedures are appropriate in the local hierarchy, the grandparent, A, should ensure their relationship to the grandchild, G, and that G has the right to the resources which they wish to have registered. These are local matters between A and G. Bush Expires December 8, 2012 [Page 3] Internet-Draft Responsible Grandparenting in the RPKI June 2012 Although A has the rights over their child's, C's, resources, it would be prudent and polite to ensure that C agrees to A forming a relationship to G. Again, these are local matters between A, C, and G. Then, it is trivial within the RPKI for A to certify G's data, even though it is a subset of the resources A delegated to C. A may certify G's resources, or issue one or more EE certificates and ROAs for G's resources. Which is done is a local matter between A and G. 4. Security Considerations This operational practice presents no technical security threats beyond those of the relevant RPKI specifications. There are threats of social engineering by G, lying to A about their relationship to and rights gained from C. There are also threats of social engineering by C, attempting to prevent A from giving rights to G which G legitimately deserves. 5. IANA Considerations This document has no IANA Considerations. 6.
