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.
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 (planning, addressing plans, transition mechanism selection).
- 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).
- Community Building & SINOG Origins: Created and nurtured a vibrant national IPv6 community that brought together all possible stakeholders—telecom operators, hardware vendors, content providers, and government regulators.
- Slovenian IPv6 Summits: Organized these highly influential summits which served as the primary collaborative forum for the region. The success and cohesion of this community laid the direct foundation for its transition into SINOG (Slovenian Network Operators Group).
- National Impact: Led the initiative that resulted in Slovenia achieving one of the highest national IPv6 adoption rates globally.
- Strategy & Testing: Co-authored the "National IPv6 Strategy" for the Slovenian Government and managed the "Go6Lab" interoperability testbed.
- Independent consultancy specializing in multimedia, A/V streaming, and ISP network design.
- Designed and implemented complex network solutions for various clients.
- Operations merged into NET42 d.o.o. in 2010.
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 of extreme events (e.g., Tomaz Humar's Dhaulagiri ascent, Ski Everest 2000).
- 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.
