IP Banning¶

FastAPI Guard provides powerful IP banning capabilities through the IPBanManager.

Automatic IP Banning¶

Configure automatic IP banning based on suspicious activity:

config = SecurityConfig(
    auto_ban_threshold=5,  # Ban after 5 suspicious requests
    auto_ban_duration=3600,  # Ban duration in seconds (1 hour)
)

Manual IP Banning¶

You can also manually ban IPs using the IPBanManager:

from guard.handlers.ipban_handler import ip_ban_manager

@app.post("/admin/ban/{ip}")
async def ban_ip(ip: str, duration: int = 3600):
    await ip_ban_manager.ban_ip(ip, duration)
    return {"message": f"IP {ip} banned for {duration} seconds"}

Checking Ban Status¶

Check if an IP is currently banned:

@app.get("/admin/check/{ip}")
async def check_ban(ip: str):
    is_banned = await ip_ban_manager.is_ip_banned(ip)
    return {"ip": ip, "banned": is_banned}

Reset All Bans¶

Clear all active IP bans:

```python @app.post("/admin/reset") async def reset_bans(): await ip_ban_manager.reset() return {"message": "All IP bans cleared"}
