Network usage types
The ratio of residential broadband to datacenter address space is the most direct indicator of what kind of proxy risk a region carries: a high datacenter share means datacenter proxies are more likely; a high residential share means home-broadband proxies and dial-up pools are.

Autonomous systems
An ASN identifies the operator of a network. Addresses under one ASN usually share risk characteristics, which is why risk controls often act on whole ASNs rather than single addresses. Operator names are not published here — the machine-readable identity is the ASN.
