Another example would be a multi ASN company which announces all prefixes from a single ASN via BGP, even though the prefixes are assigned to various AS numbers. Since the RIRs do have the information, to which AS a specific prefix is assigned to,
prefixes are not assigned to "AS" numbers, ever. prefixes are assigned to entities, as are AS numbers. ROAs and/or route(6): objects are used to tie both together - and it's in the authority of the network (prefix) holder to state which AS is allowed and expected to announce a given prefix, not the RIR. Repeat: the RIR has no say in "which AS is tied a prefix". Gert Doering -- NetMaster -- have you enabled IPv6 on something today...? SpaceNet AG Vorstand: Sebastian v.
