Summary
UKG Kronos Systems
business hr cloud corporate
KRONOS-MA is operated by UKG Kronos Systems, LLC.
What it's used for
- The address space carries corporate infrastructure, with all sampled prefixes registered under the netname
KRONOSand registrantUKG Kronos Systems, LLC; IT Core Technology. - The AS announces 38656 IPv4 addresses across 26 prefixes and 1 IPv6 prefix, while maintaining only 9 observed neighbours. This high address-to-neighbour ratio indicates an internal corporate estate rather than a transit or access network.
- Traffic from this AS consists of internal corporate endpoints and cloud services for UKG's human capital management platform, supporting office workers and web/API interactions for its global client base.
Notable
- Registrants for all sampled prefixes align with the announcer, consistently listing
UKG Kronos Systems, LLC; IT Core Technology. - The operator is the result of the 2020 merger between Kronos Incorporated and Ultimate Software, which rebranded as UKG (Ultimate Kronos Group) to form one of the world's largest cloud-based HR companies.
- The inventory is finely subdivided into 26 IPv4 prefixes within the 158.228.0.0/16 range, reflecting site-by-site segmentation typical of a large enterprise network.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
9 upstream, 0 downstream and 10 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, 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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
