Summary
The Darby Group
business corporate internal
The AS handle DDS is held by The Darby Group Co.
What it's used for

darbygroup.com(e.g.,62128.darbygroup.com,47064.darbygroup.com). - The network announces 2560 IPv4 addresses across 6 prefixes and maintains 4 observed neighbours, a ratio consistent with a private corporate estate rather than a public access or transit provider.
Notable
- Registrants for all announced prefixes are consistent with the announcer, listing The Darby Group Co. and Darby, H J under netnames
NETBLK-DARBYandDARBY-1. - The inventory consists of six IPv4 prefixes within the 198.203.0.0/16 range, with no IPv6 prefixes announced.

Internet exchanges
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 2026-11-05, 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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
