Cloud Provider IP Blocking

FastAPI Guard can automatically detect and block requests from major cloud providers. The IP ranges for these providers are only loaded when cloud blocking is enabled, improving startup performance.

Supported Providers

Currently supported cloud providers: - Amazon Web Services (AWS) - Google Cloud Platform (GCP) - Microsoft Azure

Basic Configuration

Enable cloud provider IP blocking:

config = SecurityConfig(
    block_cloud_providers={"AWS", "GCP", "Azure"}
)

Selective Blocking

Block specific providers:

config = SecurityConfig(
    block_cloud_providers={"AWS"}  # Only block AWS IPs
)

IP Range Updates

Cloud IP ranges are automatically updated daily. You can manually refresh them:

from guard.handlers.cloud_handler import cloud_handler

# Refresh IP ranges
cloud_handler.refresh()

Custom IP Checking

Check if an IP belongs to a cloud provider:

from guard.handlers.cloud_handler import cloud_handler

@app.get("/check-cloud/{ip}")
async def check_cloud_ip(ip: str):
    is_cloud = cloud_handler.is_cloud_ip(
        ip,
        providers={"AWS", "GCP", "Azure"}
    )
    return {"ip": ip, "is_cloud": is_cloud}
