  Hey there! If you scroll down in that pop up box, you'll see the following details: "You can use the following formats:

  • Single IP addresses " Example: 192.168.0.1 and 2001:db8:1a34:56cf::
  • A range of IP addresses " Example: 192.168.0.0/24 and 2001:db8:1a34:56cf::/64"

  I would look up "subnet calculator" as there are many tools that will do that for you online.
