Commune de Lyon

The municipality is tracked because AS211957 creates a monitorable network surface where routing security and upstream changes directly affect municipal internet reachability, and the TNO sovereignty program provides a replicable model for reducing proprietary lock-in in public administration—carrying both cost-efficiency gains and new partner-dependency risks that infrastructure and policy readers need to understand.

Contexte

Commune de Lyon (Ville de Lyon) operates AS211957 with a single IPv4 prefix and a digital sovereignty program that replaces Microsoft 365 with open-source tools for 5,000+ municipal staff. The evidence confirms civic scale, routing footprint, and program structure but does not map resident services to the ASN or verify migration completion. Watch for routing changes, program governance shifts, and service-to-AS mapping. This dual profile serves infrastructure monitoring and public-sector IT policy tracking.

Commune de Lyon, publicly presented as Ville de Lyon, is the municipal authority behind a small AS211957 routing footprint and a broader effort to regain control over staff tools, regional hosting, software dependency, and municipal data governance.

What It Does

  • Authority model: Municipal public authority delivering services, web presence, data governance; no commercial revenue, funded by public grants and taxes.
  • Dependency base: Over 5,000 staff rely on office/collaboration/identity workflows; residents use digital surfaces for services; Mairie de Lyon is data controller.
  • Procurement and data control: City controls software choices, hosting, subcontractors; TNO program replaces proprietary tools with open-source to reduce vendor lock-in.
  • Public funding and mutualization: TNO linked to Ville de Lyon, Métropole de Lyon, SITIV, and ANCT €2M grant; thousands of workstations in scope, not a pilot.
  • Network stewardship: AS211957 and 185.235.8.0/24 give observable routing surface; accuracy, upstream visibility, and route-security posture affect resilience assessment.

Operating Snapshot

  • Official web identity: lyon.fr legal notice states it is the official Ville de Lyon site; postal contact at 1 Place de la Comédie, 69205 Lyon Cedex 01.
  • Civic scale: INSEE lists 520,774 inhabitants (2022), 47.9 km² area, density 10,878.9 per km², 271,602 households.
  • Data-processing role: Ville de Lyon processes personal data for public-service missions; Mairie de Lyon named controller.
  • Routing footprint: AS211957, allocated 2021-01-22, announces 185.235.8.0/24 (256 IPv4), no IPv6; upstream AS30781 Free Pro SAS; ROA signed/valid per IPIP.
  • Digital-sovereignty program: Announced 2025-06-23: TNO platform, regional datacenters, €2M ANCT, progressive replacement of MS Office with free tools.
  • Deployment economics: Banque des Territoires (2026-03-10): refused M365, built suite with partners; first-year cost ≈€368k; redirected avoided sub costs to change management.
  • Partner deployment signal: SITIV (2025-07-15): TNO uses Jitsi, OnlyOffice, Nextcloud; hosted in regional datacenters; used by several thousand agents in 7 authorities.

Control Surface

  • ASN registry identity: RIPE: AS211957, org-name COMMUNE DE LYON, status ASSIGNED, maintained under lir-fr-communedelyon-1-MNT.
  • IPv4 routing footprint: Single prefix 185.235.8.0/24, 256 IPv4; no known IPv6; ROA signed/valid and IRR valid in observed view.
  • Interconnection context: Upstream AS30781 Free Pro SAS; import/export entries include AS5410, AS43100; routing-context, not hosting claims.
  • Route-security signal: Prefix has RPKI ROA valid and IRR valid; ASPA and conflict state need live refresh.
  • Mutualized public-sector platform: TNO includes identity, signature, safe storage, communication, e-learning, document sharing, carried by SITIV.
  • Staff software stack: Open-source components Jitsi, OnlyOffice, Nextcloud, Linux, PostgreSQL, Firefox; affects compatibility and training.
  • Data governance: Mairie de Lyon controller; commitments on security, minimization, subcontractor, transfer, rights-handling.
  • Official website maintenance: Stratis handles conception, development, maintenance of lyon.fr; separate from AS211957 routing.

Watchpoints

  • Service-to-AS mapping: lyon.fr, e-services, arrondissement sites not mapped to AS211957; identity verified separately.
  • Live routing posture: Refresh BGP announcements, upstreams, ROA/IRR/ASPA state, prefix conflicts, IPv6 origination near-publication.
  • Migration completion: No post-target audit confirming early-2026 near-complete migration; verify adoption and exceptions.
  • Program governance: Depends on Lyon–Métropole–SITIV coordination, ANCT support, regional hosting; changes alter sustainability.
  • Tele-service data handling: Broad data-protection commitments may not cover service-specific subcontractors or hosting arrangements.
  • Adoption-count boundary: Figures differ: Banque des Territoires 5,000 workstations; Ville de Lyon several thousand agents in 9 authorities; SITIV several thousand in 7. Keep tied to source.

Signal Map

Signal Map

  • Why tracked: The municipality is tracked because AS211957 creates a monitorable network surface where routing security and upstream changes directly affect municipal internet reachability, and the TNO sovereignty program provides a replicable model for reducing proprietary lock-in in public administration—carrying both cost-efficiency gains and new partner-dependency risks that infrastructure and policy readers need to understand.
  • Object role: The institution delivers municipal public services and governs digital tools for more than 5,000 staff. In internet infrastructure evidence, it appears as the organisation behind AS211957 and the 185.235.8.0/24 prefix, though no resident-facing services are confirmed to run on that network. Its broader role includes data controller responsibilities, procurement of open-source software, and leadership of the Territoire Numérique Ouvert (TNO) collaboration suite with regional partners.
  • Impact note: Changes in AS211957 routing posture can alter the technical resilience assessment of a city serving half a million people; shifts in the TNO program’s governance, funding, or software stack can affect municipal service continuity, vendor market dynamics, and the perceived viability of open-source public-sector alternatives across Europe.
