AS11823 LORDABBETTCO

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 handle LORD-ABBETT to 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.
