AZ511722 - Generally Available: Azure Firewall Updates - IP Group limit increased to 600 per Firewall Policy

• Reduce rule complexity by replacing long lists of IPs with more well-organized IP Groups, making rule sets easier to manage and audit. 

• Supports large-scale architectures and microsegmentation: Enterprises often manage hundreds of app tiers, networks, and subnets. 

• Improves troubleshooting: Named groups make it easier to understand rule intent (e.g., HR-Network, IT-Network, etc.) in logging during debugging or reviews.
