Summary
Lord, Abbett & Co. LLC
enterprise legacy
LORDABBETTCO is Lord, Abbett & Co. LLC, the independent US investment-management firm. ARIN places the org at 90 Hudson Street, Jersey City, New Jersey — the company's long-standing headquarters across the river from Manhattan — and dates the ASN to January 1999.
What it's used for
- A single-tenant corporate network for an asset manager. There is no customer-facing service here and nothing is resold: the AS exists so the firm can hold provider-independent space and reach the internet through more than one path if it chooses.
- RIS sees exactly 1 IPv4 prefix / 256 addresses, no IPv6, and 2 observed neighbours. A single /24 with two upstreams is a textbook enterprise multi-homing arrangement — the smallest amount of space that can be routed, announced twice for resilience rather than capacity.
Notable
- The one announced prefix,
204.128.232.0/24, is ARIN-registered under the handleLORD-ABBETTto LORD, ABBETT & CO. LLC. Registrant and holder are the same firm, the space is single-RIR, and there is no third-party registrant anywhere. Nothing in the inventory resembles leased or brokered address space. - No reverse DNS was returned on the two addresses sampled. Two out of 256 is a sample and nothing follows from it — the zone may well be delegated and populated elsewhere in the /24.
Interesting
- Financial firms are unusually dense in this part of the AS number space, and most of them look exactly like this: one /24, one or two upstreams, self-registered, quiet. The routing table tells you almost nothing about a company of this size, because a firm managing large sums of money still only needs a couple of hundred public addresses for its own edge.

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 2026-10-25, 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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
