the reason Cortex® Xpanse™ attributed that asset to your company.
Cortex Xpanse uses a variety of methods to attribute IP range
assets to organizations. These reasons include:
—The IP range’s
registry information mentions information about your organization.
Cortex Xpanse pulls from all regional internet registry databases, including
ARIN, RIPE, APNIC, LACNIC, and AFRINIC. Registry information in
your Cortex Xpanse Expander instance is updated approximately biweekly.
—An autonomous system
number (ASN) assigned to you advertises the IP range as a BGP prefix.
—That IP range advertised
one of your certificates.
—A DNS record points to an IP in
that IP range. Cortex Xpanse gets its domains and DNS data from
a combination of active and passive global collection techniques.
—The asset was on an
IP address list provided to Expanse by your organization or by Expanse
for a reason other than those listed above.
