Quoting Geoff Huston via rssac-caucus on Saturday October 05, 2024:
"since there isn´t an IANA RPKI TA"
I agree with you that these addresses are "special purpose" addresses and they should exist in the IANA Special Purpose Address Registries. But at that point why shouldn't IANA run its own RPKI TA and announce these and the other addresses that are listed in these registries? If the address is not globally routable it could issue a ROA with AS0. Otherwise it could announce ROAs with the relevant originating addresses.
In my view, if these are addresses in an IANA registry then the RPKI structure should accurately reflect that.
I wasn't a party to the discussions that lead to the current RPKI structure, but this question has come up recently in other contexts where issuing ROAs for IANA reserved address space has been an issue. I am not sure the right forum to explore the issue of IANA-issued ROAs further, but I do wonder - under David's proposal - what would be the threshold for critical infrastructure that merits IANA reservation? Once you open the door here I have to assume there is a slippery slope of other things that warrant similar consideration. kim
