Reviewer: Gyan Mishra Review Date: 2021-01-06 IETF LC End Date: 2021-01-04 IESG Telechat date: Not scheduled for a telechat Summary: This document updates RFC 3552 Security Considerations for Transient numeric identifiers employed in network protocols. Currently RFC 3552 does not address transient network identifiers exploitation by pervasive monitoring. Major issues: None Minor issues: My suggestion is to maybe have examples section similar to RFC 3552 that gives examples of the security implications of the various types of transient numeric identifiers. An example for IPv6 IID would be using modified EUI64 versus RFC 4941 privacy extension or even RFC 7217 / RFC 8064 stable IID. Nits/editorial comments: None
