Profile

Thirty years in internet infrastructure, spent largely on the gap between what a standard says and what an operator can actually deploy on a Tuesday morning.

Primary co-author of RIPE-554 — the IPv6 procurement requirements adopted by national governments and multinationals — and of its RIPE-772 update. Co-author of three IETF RFCs, one of them a Best Current Practice. Vice Chair of the RIPE Programme Committee, and chair of the Nominating Committee that selected the RIPE Chair and Vice Chair in the 2024–2025 cycle. Co-founder of the Global NOG Alliance and lead of its Keep Ukraine Connected task force.

Earlier, part of the small team that produced the first live video stream from the Himalayas — the 2000 ski descent of Mount Everest — which remains the most unusual line on this CV.

Signature work

RIPE-554 · Requirements for IPv6 in ICT Equipment

Primary co-author · Best Current Practice · updated as RIPE-772

  • Broke the procurement deadlock that stalled IPv6 for years: vendors would not ship what buyers did not ask for, and buyers had no common language to ask in.
  • Adopted into public procurement by governments including Slovenia, Sweden and Germany, and by multinational buyers.

Keep Ukraine Connected

Task force founder and lead · Global NOG Alliance · since February 2022

  • Called on the operator community to donate hardware for rebuilding Ukrainian network infrastructure; close to two tonnes of equipment was collected within weeks and the first van-load personally delivered into the country.
  • Still running: matching donated equipment to the operators who need it.
