AS11189 CFL-AS1

CFL-AS1 is registered to Caliber Home Loans, Inc., a US residential mortgage lender and servicer, with ARIN listing the organisation at 1525 S Belt Line Rd in Coppell, Texas. This is a corporate network, not a service provider.

What it's used for

Enterprise infrastructure for a financial-services firm. RIS observes four IPv4 prefixes and 1,024 addresses, all of it one 199.204.116.0/22 plus three of its constituent /24s announced as more-specifics; there is no IPv6 in the observed routing. Every prefix is registered to the same first-party ARIN block (CAL-FO-SN1), so nothing here is leased-in space.

Two observed BGP neighbours is the classic multihomed-enterprise pattern: a pair of transit providers for redundancy, no peering estate. A /22 is roughly what a lender needs for public-facing borrower portals, VPN concentrators for staff and branch offices, and mail — the bulk of a mortgage business's compute is internal or in a cloud that this AS never carries.

Notable

The deaggregation is doing work: announcing the /22 alongside its /24s is the usual way an enterprise steers inbound traffic across two upstreams without asking either of them for anything special.

Interesting

ARIN records a registration date of 2010 for the ASN, so the low AS number should not be read as evidence of a long-lived 1990s network. Numbers in this range circulate.
