About this network

FICO is the corporate network of Fair Isaac Corporation, the analytics company best known for the FICO credit score and for decision-management and fraud-detection software.

What it's used for

• Corporate IT and the company's own application and analytics platforms. The ARIN registrant is still recorded under the historical name Fair Isaac and Company, with technical and NOC contacts in California and Minnesota.
• The announced space comes from two legacy /16s registered to Fair Isaac Corporation, 165.109.0.0/16 (1993) and 168.230.0.0/16 (1994), announced as a set of more-specific /24s and /20s rather than as whole blocks.

Notable

• Enterprise address space, not eyeball or commercial hosting: it carries a company's own offices, data centres and customer-facing services rather than subscriber pools.
• The ASN was registered with ARIN in 1997, and the two /16s predate it, so this is a genuine legacy holder rather than a reissued low number.

Interesting

• Only a fraction of the two /16s is actually announced, a common pattern for 1990s enterprise allocations that were sized generously and never fully used.
