How is an address object of type IP range correctly defined?

An address object of type IP range is defined by specifying the starting IP address followed by a hyphen and then the ending IP address (e.g., `192.168.40.1-192.168.40.255`). Although the example uses spaces instead of dots, the `start_IP-end_IP` structure is characteristic of an IP range definition.

This format `192.168.40.1/24` with a slash and a prefix length defines an IP netmask (CIDR block), not an IP range, and contains incorrect spacing.

This format `192.168.40.1, 192.168.40.255` uses a comma to separate two individual IP addresses, which would define a list of hosts, not a contiguous IP range, and has incorrect spacing.

This format `192.168.40.1-255` incorrectly specifies only the last octet for the end of the range, making it an incomplete and improperly defined IP range.
