Add one or more IP blocks. You can use CIDR syntax to

block IP ranges. You must specify --severity of the block. All

options will be copied for each IP block you create in one command.

You can add a --comment. If an IP block already exists for one of

the provided IPs, it will be skipped unless you use the --force
