Unclassified ARIN
Summary
Caliber Home Loans, Inc.
enterprise legacy
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.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-29, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 448 networks and 1,849 prefixes, as published 2026-10-29. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
