March 2025 achievements focused on enhancing IP-based routing analytics and privacy-conscious conventions. Delivered two substantive contributions across OpenTelemetry repos: - Open-telemetry/opentelemetry-collector-contrib: GeoIP Attribute Configuration for IP Address Identification in geoipprocessor, enabling a configurable attributes parameter and defaulting to source.address and client.address with client.address taking precedence. Added commits to support the new parameter and default behavior. - Open-telemetry/semantic-conventions: Semantic enhancements introducing app.installation.id for application installations and updating device.id usage to require opt-in due to privacy considerations, with accompanying documentation and registry updates. These changes were implemented with a focus on business value—more accurate geoIP lookups for routing, access control, and analytics; privacy-aligned device identifiers; and clearer conventions for downstream analytics.
