Want more granular control?

Instead of blocking an entire geographic region, it might be more effective to block specific internet providers based on their autonomous system number (ASN). Check out as-ip-blocks for more information.

Use cases

• Block countries at the firewall (for compliance or security reasons)
• Geo-based access control and traffic routing
• Network research and statistical analysis
• Threat hunting and security research
