Fred: Thank you for commenting on the missing examples in trill-irb. We'll see about adding those examples. Sue (TRILL co-chair) -----Original Message----- From: fred@cisco.com [mailto:fred@cisco.com] Sent: Wednesday, April 06, 2016 11:01 AM To: draft-ietf-trill-irb.all@tools.ietf.org Subject: IPv6 examples in draft-ietf-trill-irb Hello: I'd like to bring something to your attention with regard to draft-ietf-trill-irb, if I may. It uses IPv4 examples (examples using addresses in 192.0.2.0/24, 198.51.100.0/24, or 203.0.113.0/24), but presents no IPv6 examples (which would use 2001:db8::/32, as specified in RFC 6890). This suggests that at some future time the protocol will likely need to be updated to use IPv6 in addition to IPv4. draft-robachevsky-mandating-use-of-ipv6-examples makes a very practical suggestion, which is that drafts should consider IPv6, as it is the direction the Internet is headed, and therefore provide either only IPv6 examples or both IPv4 and IPv6 examples. This has not been agreed to in the IETF, nor is it a mandate in any sense. However, it seems practical. I can imagine that you just didn't think about IPv6, on the assumption that it is not a current reality in the Internet; while not true, that is a common perception. However, as https://www.vyncke.org/ipv6status/compare.php?metric=p&countries=be,ch,us,pt ,de,gr,lu,pe,ec,ee,jp,fr,cz,my,fi,no,br,ca,ro,nl displays, Google, APNIC, and Akamai are reporting that at least 39 countries worldwide have non-negligible IPv6 deployment (at least 1% of the traffic each of them sees uses IPv6 in those markets), 20 of them have at least 5%, and, in one case and one measurement, over 50% of their traffic. Additionally, AT&T, Comcast, Google, and T-Mobile indicate that a significant pecentage (around half to three quarters) of their mobile handsets or home computers are using IPv6 - in some cases, accessing IPv4 sites only through NAT64 translation. In that spirit, would you please consider duplicating your IPv4 examples, or augmenting them, to display both the IPv4 and IPv6 variants? Thanks. Fred
