Assets are machines that are deployed on the Internet that are a part of an organization’s externally facing infrastructure. They represent real-world observations of active systems.
The machines can be identified as the following types of assets:

It appends a slash character to the address and the decimal number of leading bits of the routing prefix, e.g., 193.168.2.0/24 for IPv4, (193.168.2.0-193.168.2.255) and 2001:db8::/32 for IPv6.
