What it's used for
- The address space carries a mix of corporate and third-party infrastructure, with netnames including
ATOS-NAMERICA-INET,USROYALINS,TWTC-NETBLK-4, andNETBLK-GG-DBN-CORP. - The AS announces 23,552 IPv4 addresses across 13 prefixes while maintaining only 4 observed neighbours, a ratio that suggests an internal corporate estate or limited transit role rather than a large access network.
Notable
- Registrants vary significantly from the announcer, including Arrowpoint Capital, Level 3 Parent, LLC, Genix Group, Incorporated, and Conduent Business Services, LLC, alongside Atos IT Solutions and Services Inc.
- The address inventory is fragmented, with the largest block being a /19 and the remainder consisting of /20s, /23s, and /24s, indicating a collection of distinct allocations rather than a single contiguous range.

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 2026-10-26, 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
