In 2003, Alireza Vaziri stepped into the Internet industry as the technical support of an ISP. It was around 2006 that he found his interest in network and system engineering. He worked with different ISPs and organisations as a System/Network Administrator until 2016 before going into cybersecurity. Back in those days, many ISPs in the Middle East were facing Internet abuse and attacks, so botnets and DDoS caught his attention as a challenge of the region.
Alireza has spoken at several conferences, including RIPE and MENOG Meetings, on the reduction of abuse in networks. He is currently helping Local Internet Registries reduce their network attack surface and protect themselves from modern attacks. Alireza also serves as Co-Chair for the Anti-Abuse Working Group and he deeply believes that most of the security-related issues could be addressed during RIPE Meetings with the help of people from different regions.
Jan Žorž started his professional career in the RS-232/VAX VMS world in 1992 and continued through Novell and Windows environments all the way to Solaris and other UNIX derivatives that represent the native environment for the majority of his projects.
Jan is one of the pioneers of SiOL, the Slovenian national ISP, and has been involved in the organisation from the beginning. Among other activities, he began experimenting in 1997 with Internet streaming multimedia content. Based on these experiments, he successfully accomplished projects such as “Dhaulagiri ’99 Live” (an Internet multimedia transmission of Tomaz Humar’s solo climb of the south wall of Dhaulagiri (called Death Zone) in the Himalayas), “Ski Everest Live 2000” (an Internet live-video transmission and monitoring of extreme skiing from the summit of Mt. Everest by Davo Karnicar) and other similar projects. Together with two other members of team “Dhaulagiri ’99 Live”, Jan received a media award/statue “Victor” for special achievement.
For the last seven years, Jan has been working as a consultant in the IT field, specialising in IPv6. He co-founded the Go6 Institute (not-for-profit), a Slovenian IPv6 initiative whose main objective is to raise IPv6 awareness in Slovenia and alert the community to the fact that we are approaching extensive changes on the Internet.
Due to the Go6 Institute, Slovenia is currently leading the EU as the country most prepared for IPv6 (according to the RIPE NCC’s IPv6 RIPEness study). Jan has been invited to present around the world on his work, the model of the Go6 platform, and IPv6 awareness raising and deployment at the national level. These speaking engagements have included conferences such as many RIPE Meetings and the Google IPv6 Implementors Conference 2010, Internet Governance Forum meetings, World IPv6 Congresses in Paris and London as well as national forums in Germany, Greece, Norway, Macedonia and many others.
Jan is also primary co-author of very successful procurement (specification) paper, published as an official RIPE Best Current Practice document RIPE-501, entitled “Requirements For IPv6 in ICT Equipment”. This document is translated into more than 10 languages and is used around the world by enterprises and governments when requesting IPv6 in ICT equipment purchases. RIPE-501 was recently replaced by RIPE-554, also co-authored by Merike Kaeo and Sander Steffann.
