(Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-cdni-uri-signing/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- Thank you for the work put into this document. Special thanks for the doc shepherd write-up , which was really useful about the WG history. Please find below one blocking DISCUSS points (which should be solved easily), one non-blocking COMMENT point (but replies would be appreciated), and some nits. I hope that this helps to improve the document, Regards, -éric == DISCUSS == -- Section 2.1.10 -- About "Client IP (cdniip) claim", I really wonder whether this could be used in real life as some IPv4 Carrier-Grade NAT (CGN) have a large pool of "public" IPv4 addresses that could select different public IPv4 addresses if badly designed. How will it work with dual-stack UAs where some connections could be over IPv4 and some over IPv6 ? Now to mention a dual-home (Wi-Fi & mobile data) UA ? Or what if the dCDN is between the UA and the CGN (assuming that the uCDN or CSP are upstream of the CGN) ? Also, "If the received signed JWT contains a Client IP claim" uses singular rather than "one or several" I also noted that Section 7 (security considerations) puts some restrictions on the usefulness of cdniip. I would welcome some applicability statements on the use of cdniip. ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- == COMMENTS == -- Section 1.3 -- To be honest, I fail to understand the meaning (hence the value) of figure 3. == NITS == I am afraid that the email address kleung@cisco.com is outdated. -- Section 1 -- Is CDNI "interconnected CDNs (CDNI)" or "CDN Interconnection (CDNI)" ?
