Professional Profile
Senior Network Engineer & IPv6 Architect with over 30 years of experience in ISP network design, protocol standardization, and internet governance. Renowned for designing complex IPv6 transition architectures for large-scale operators, bridging the gap between IETF standards and operational reality. A trusted leader in the global internet community, currently holding high-level governance roles within RIPE and the Global NOG Alliance.
Author of RIPE-554, the industry-standard document that revolutionized global IT procurement by mandating IPv6 support in hardware tenders, effectively breaking the "chicken-and-egg" cycle of deployment.
Global Impact & Industry Footprint
Beyond presentations, my work has focused on shaping global technical internet policy, driving the adoption of open standards, and deploying resilient infrastructure in emerging markets.

Professional Experience
- Leading research and development of network protocols and automation solutions to accelerate global IPv6 deployment.
- Architecting strategies for network operators to manage complex Dual-stack environments and facilitate the transition to IPv6-only architectures (NAT64/DNS64, 464XLAT).
- Liaising with the global technical community to integrate 6connect solutions with operational best practices.
- Strategic Consultancy: Providing high-level architectural design for ISPs, content providers, and governments, focusing on the full lifecycle of IPv6 adoption.
- Technical Training: Delivering specialized workshops on routing security (MANRS), DNSSEC, and IPv6 troubleshooting.
- Note: NET42 succeeded the "Pragma" consultancy in 2010.
- Co-founded the alliance to support and connect Network Operator Groups (NOGs) worldwide.
- Task Force Leader: "Keep Ukraine Connected" (Started Feb 2022). Orchestrated the collection and delivery of critical network equipment to operators in Ukraine to maintain internet resilience during conflict.
- Member of the Deploy360 team. Responsible for "Operational Engagement"—bridging the gap between IETF standards and network operators.
- Facilitated the creation of "Best Current Operational Practices" (BCOP) documents to capture and share community knowledge.
- Promoted the deployment of open standards: IPv6, DNSSEC, TLS, and Routing Security (MANRS).
- National Strategy: Co-authored the "National IPv6 Strategy" (2010), commissioned by the Ministry of Higher Education, Science and Technology.
- Go6Lab: Established an accredited "IPv6 Ready" testing facility; performed critical early-stage interoperability testing for mobile hardware (LTE) and ISPs.
- Real-World Deployments: Coordinated the "World IPv6 Launch" for Slovenian operators and successfully advocated for the IPv6 enablement of the 2012 National Election results.
- Community & Summits: Organized influential IPv6 Summits hosting global pioneers including Robert Hinden, Patrik Fältström, Daniel Karrenberg, and Martin Levy.
- Independent consultancy specializing in multimedia, A/V streaming, and ISP network design.
- Operations merged into NET42 d.o.o. in 2010.
Pioneering Internet Projects (SiOL)
Part of the core team that executed the first-ever live video internet stream from the Himalayas. Broadcasted Davo Karničar's historic, first uninterrupted ski descent from the summit of Mt. Everest (8,848m) to Base Camp. Managed the complex logistics of satellite uplinks and real-time encoding at extreme altitude.
Provided live internet multimedia coverage of Tomaž Humar's legendary solo ascent of the Dhaulagiri south wall. Recipient of the Viktor for Special Achievements (1999), Slovenia's highest media honor, awarded for the "project of monitoring the ascent of alpinist Tomaž Humar via the internet".
Earlier Experience
- Select Technology d.o.o. (2002-2006): Senior System Administrator. Managed Unix/Linux/FreeBSD systems and ISP operations.
- SiOL (Telecom Slovenia) (1996-2001): System Administrator & Technical Marketing. Built the initial internet infrastructure (Solaris/Sun). Pioneered live internet streaming (e.g., Ski Everest, Dhaulagiri).
- Telecom Slovenia (1994-1996): Novell Administrator.
- TAC Communications (1992-1994): Network Technician (VAX/VMS, 10BaseT).
Publications & Standards (Global Impact)
This document is widely considered the definitive global standard for IPv6 procurement. It solved a critical industry deadlock by providing a unified "copy-paste" set of technical requirements for public and private tenders. It has been translated into over 10 languages and adopted by national governments (e.g., Slovenia, Sweden, Germany) and multinational corporations.
