I performed a ‘masscan’ on to find any hosts within the private space that might not be accounted for. I found 11199 hosts in total. Most of these are accounted for but I wish to scan all of these hosts.

The limits, as I understand them, are 4096 hosts per target list (aka 4096 hosts per scan). Do I simply break this list of 11199 hosts up into chunks of 4096 hosts and perform a scan on each of them? Is there some awesome way of using the CLI to do this and then initiate scans for each of the targets that were created?

Any advice from an experienced user would be appreciated.
