IP Protection is a new SKU for Azure DDoS Protection that is designed with SMBs in mind and delivers enterprise-grade, and cost-effective DDoS protection. You can defend against L3/L4 DDoS attacks with always-on monitoring and adaptive tuning that ensure your application is always protected. With IP Protection, you now have the flexibility to enable protection on a single public IP. Azure DDoS Protection integrates seamlessly with other Azure services for real-time alerts, metrics, and insights to strengthen your security posture.
If you have only a few public IPs in your environment, then you can start with IP protection SKU which can be enabled directly on the Public IP resource, and you only pay for that protected resource. The cost is a fixed 199$/month for each public IP resource protected with no additional variable costs. Prices may vary by region. Billing for IP Protection will be effective starting on February 1, 2023. Please see full detailed pricing list here Azure DDoS Protection Pricing | Microsoft Azure
