Reviewer: Dan Romascanu Review result: Has Nits Summary: Ready with Nits (this review applies to both Gen-ART and OPSDIR. This is an informational document reviewing advantages and disadvantages of the five most prominent IPv4aaS technologies. The document is explicitly targeting network operators, so it is useful and recommended that operators dealing with one or more of these technologies or evaluating their introduction read it carefully. I liked Section 4.5 which includes some very useful Typical Deployment and Traffic Volume Considerations and Section 5. Performance Considerations. Major issues: Minor issues: Nits/editorial comments: 1. I am not sure whether this Informational document needs any of the capitalized key words as described in BCP14 [RFC2119] [RFC8174] mentioned in Section 1.1 2. Another pass to make sure that acronyms are expanded at first occurrence would be useful. For exemple: UE in section 2.1 3. It is not clear how Table 2 should be read. What means an X? I guess it is supposed to say 'it applies, no data model' but this should be explained 4. Section 4.4.1 - I am slightly uncomfortable with the URLs for free open-source implementations being included in the text. Maybe an Appendix would be a better place. Or at least use informative references. -- last-call mailing list last-call@xxxxxxxx https://www.ietf.org/mailman/listinfo/last-call
