A CA under your RIR
Delegated, not shared.
- Your own certificate authority
- Delegated from RIPE or another RIR
- ROAs you create and revoke yourself
Most networks that should sign their routes do not, because the software wants a server, a repository and a maintenance plan. We run those. You keep the certificate authority and the decisions; the parts nobody wants to operate are ours.
Delegated, not shared.
RRDP and rsync, kept up.
One endpoint, every VRP.
For a CA, yes — a ROA says which AS may originate a prefix, so the prefix has to be yours. The RTR endpoint is useful to anyone with routers, whether or not they hold address space.
Yes. The CA is delegated to you from your RIR; moving it elsewhere, or taking it in-house, is a change at the RIR and does not need our cooperation.
