One problem with DiS is that assumes that address records in the additional section *always* come from the delegating zone (see how the hash is created). This is not how DNS works. Address records can, correctly, come from other sources, even when the name is *below* the zone cut. Take a server that serves example.net and sub.child.example.net. That A record comes from sub.child.example.net not example.net when the name of the server is a.sub.example.net. child.example.net NS a.sub.example.net a.sub.example.net A 1.2.3.4 Mark > On 4 Nov 2020, at 15:31, fujiwara@jprs.co.jp wrote: > > I submitted draft-fujiwara-dnsop-delegation-information-signer-00. > > Name: draft-fujiwara-dnsop-delegation-information-signer > Revision: 00 > Title: Delegation Information (Referrals) Signer for DNSSEC > Document date: 2020-11-03 > Group: Individual Submission > Pages: 6 > URL: https://www.ietf.org/archive/id/draft-fujiwara-dnsop-delegation-information-signer-00.txt > > DNSSEC does not have a function to validate delegation information. > I think it is a large missing peace of DNSSEC. > > I have a question why we did not include signature validation function > to delegation information ? > > Probably, because it is non-authoritative information. > Or, because it was difficult to define the necessary and sufficient > delegation information. > > It is now widely agreed (although not explicitly documented) that the > delegation information is the information used for name resolution and > does not result in name resolution. > > We have a word "in-domain" glue which is the necessary and sufficient glue. > > And the idea may offer the signature for root priming data. > > If someone interested the document, I would like time slot at dnsop WG > meeting. > > Regards, > > -- > Kazunori Fujiwara, JPRS <fujiwara@jprs.co.jp> > > _______________________________________________ > DNSOP mailing list > DNSOP@ietf.org > https://www.ietf.org/mailman/listinfo/dnsop -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@isc.org
