Recent reporting highlighted google to use uk and eu user ip addresses for ad personalization. Google has begun notifying advertisers that it will start using IP addresses for ad measurement and personalization across the European Economic Area (EEA), the UK and Switzerland on or shortly after August 3, 2026. IP addresses are received by online services on nearly every request, and the practice is routine across much of the world.

  • Review whether the issue, advisory, or attack pattern is relevant to your environment, suppliers, or exposed systems
  • Patch, harden, or validate logging and monitoring coverage where applicable
  • Translate the development into specific ownership, policy, and evidence requirements instead of leaving it as background policy tracking
  • Monitor follow-on reporting or primary-source updates for scope expansion, implementation guidance, or stronger enforcement signals
