How Azure IP Changes Are Tracked
The tracker continuously processes the official Microsoft Azure Service Tags dataset to generate weekly diffs and a searchable change history, enabling teams to quickly understand what changed and integrate updates into security and automation workflows.
🔄
Official Microsoft Data, Automatically Synced
The platform pulls the official Azure Service Tags dataset every Monday at 00:00 UTC via GitHub Actions. Each run generates a current snapshot, weekly diffs, and timestamped history so you always know when IP ranges are added or retired.
🛡️
Built for Security & Networking Teams
Search by service, region, or IP address to quickly identify range changes and understand what changed and when. Detailed change sets can then be exported from the Change History for firewall and network automation.
🤖
API & Automation Friendly
All datasets are published on GitHub Pages under /data. Automation tools can discover available updates, retrieve precise diffs from historical snapshots, or queue downloads using the manifest. Sample scripts for PowerShell, Python, and other languages are provided.

Frequently Asked Questions (FAQ)
What makes this different from Microsoft's raw file?
▼Microsoft publishes a single JSON, but this tracker layers on weekly comparisons, searchable UI, analytics, and long-term archives. You can quickly answer questions like "When did AzureCloud.eastus change?" without diffing files manually.
Can I monitor Azure IP changes without forking?
▼Yes. Point your scripts to https://eliaquimbrandao.github.io/azure-service-tags-tracker/data/ and query the JSON endpoints directly. No API keys, rate limits, or authentication flows required. Check out our API Usage Examples for scripts in Python, PowerShell, and more.
How do I get alerted when Service Tags move?
▼We are implementing a feature that will allow users to receive alerts for changes (ETA: Q3 CY 2026).
