Reviewer: Nicolai Leymann Review Result: Ready Draft: draft-gont-numeric-ids-sec-considerations Hi, I'm the designated DNS Directorate (dnsdir) reviewer for this document. The draft updates RFC3552 requiring future RFCs to contain a vulnerability assessment of their transient numeric identifiers. The document lists common flaws in the generation of transient numeric identifiers. Based on that it defines requirements for future protocols specifications using transient numeric identifiers. The draft itself is not specific to DNS but uses DNS Transaction IDs as one of the examples for underspecified transient numeric identifiers. Overall, I think this draft is well written, easy to understand and ready for Publication.
