Method and limits
- Entry counts
- Each matching CSV range counts once. A range is not necessarily a BGP route.
- Associations
- ASN and country assignments come from the matching CSV record.
- Address coverage
- The sum of ordered, non-overlapping matching CSV ranges. Coverage measures address space, not devices or active hosts.
- IPv6 addresses
- Exact addresses764,
742, Address space in the data. Not a count of active devices.044, 728, 936, 723, 078, 410, 714, 218, 500
The tag reflects the ASN’s exported academic classification, rather than a claim about the user of an individual IP.
Classifications can overlap and use a fixed data release. Membership can change after collection; a non-match is not a safety verdict.
