Dear All, I have read the draft. (Only its main text, not the appendices.) I feel that it is quite comprehensive, it covers a lot of aspects of IPv6 deployment and provides a good overview. I have not found any significant issue, but only nits (see below). Perhaps a WGLC may follow. Best regards, Gábor ------------------ Nits ------------------ I was taking notes during reading. The majority of them are technical. For some reason unknown to me, some references did not became links in the htmlized version. Section 2.3. [W3Tech] Section 3.1. [APNIC2] Section 3.3 [NST_1] -- should be a link [BGR_1] -- should be a link [CNLABS_1] -- should be a link Typo: IPv6-enablesd --> IPv6-enabled Grammar: A poll ... show --> A poll ... shows Section 3.3.1 DSN --> DNS Section 4.2 [I-D.ietf-v6ops-transition-comparison] -- should be a link While it cannot be always the case, IPv6-only transition technologies such as 464XLAT require much less IPv4 public addresses [I-D.ietf-v6ops-transition-comparison <https://datatracker.ietf.org/doc/html/draft-ietf-v6ops-ipv6-deployment#ref-I-D.ietf-v6ops-transition-comparison>], because they make a more efficient usage without restricting the number of ports per subscriber._This_ contributes to reduce troubleshooting costs and to remove some operational issues related to permanent black-listing of IPv4 address blocks when used via CGN in some services. For example, Sony Play Station Network or OpenDNS imply a higher rotation of IPv4 prefixes in CGN, until they get totally blocked, which means extra CAPEX in new IPv4 transfers. What does "This" refer to? - If it refers to 464XLAT, then I do not understand it. (Or, I think just the opposite is true: as the same public IP address and port number is ones used by a given user and then by another.) - If it refers to MAP-E/T, then it should be made clear. Section 7.1.1 On average, looking at the global statistics, the IPv6 traffic percentage is currently between 30% and 40% of_IPv6_. Perhaps: On average, looking at the global statistics, the IPv6 traffic percentage is currently between 30% and 40% of*the traffic*. Section 7.1.3 an high percentage --> a high percentage Section 7.2. govern supporting --> governmental supporting Section 7.4.1 [APNIC5] -- should be a link (twice) [APRICOT <https://datatracker.ietf.org/doc/html/draft-ietf-v6ops-ipv6-deployment#ref-APRICOT>] highlights how when a difference in performance exists it is often related to asymmetric routing issues. Perhaps "how when" is not proper. Other possible explanations for a relative latency difference lays on the specificity of the IPv6 header which allows packet fragmentation. I do not understand this. Section 7.4.2. [FB] -- should be a link Section 7.5. Some hints are in the paper [ComputSecur <https://datatracker.ietf.org/doc/html/draft-ietf-v6ops-ipv6-deployment#ref-ComputSecur>].
