The IETF began its 30th anniversary year with a very memorable meeting in Buenos Aires, Argentina. This was only the second the IETF has meet in the southern hemisphere. In addition to drawing a large number of local participants, it included a relatively high number of remote attendees.

Our cover article this issue was prompted by a presentation and debate that took place in the sunset4 Working Group on the subject of declaring IPv4 Historic. Read Lee Howard’s and Geoff Huston’s perspectives and make up your own mind!

In addition, we have Working Group updates from L3SM and TAPS, observations from one of the Internet Society Fellowship to the IETF Programme participants, a view from the pre-IETF Hackathon, and an article about a potential new technology direction for the IETF, namely Intelligent Transportation Systems.

Our regular columns from the IETF, Internet Architecture Board, and Internet Research Task Force chairs, and coverage of hot topics discussed during the plenary meetings wrap up the issue.

Finally, I’m thrilled to announce our newly redesigned website has been launched. Check it out at I hope you find the IETF Journal content more accessible and interactive.
