Overview

Every registered or announced IPv4 and IPv6 range with the organization that uses it. Where a network operator has assigned a block to a customer, the row names the customer rather than the operator: a hotel, a bank or a school inside a telecom's space. Where the operator keeps a block for its own subscribers, the row names the operator.

name is the organization, domain its own registrable domain where one is known, type the kind of organization and country the country it is registered in. asn, as_name, as_domain and as_type are the AS announcing the range, as the ASN database publishes them, so a row whose company is not its AS's holder is a customer of that network.

It names the businesses behind your traffic, with a domain to match against the accounts you already have, and tells an office network from consumer broadband or a hosting provider.
