I'd also check on the rationale for this large list. I have seen clients wanting to import what they used on an old firewall for public IP blacklist addresses. That content and feature is generally much better addressed via the use of Cisco's Security Intelligence feeds which are automatically updated every 2 hours by default.
Hi Marvin, thanks for your response. I did notice the security intelligence feature where we can upload IP lists to blacklist or whitelist IP addresses, but there is no way we can permit those IPs from the specific host address.
