Summary
ModusLink Corporation
enterprise legacy
MODUSLINK is ModusLink Corporation, a global supply-chain and e-commerce fulfilment provider and the operating subsidiary of Steel Connect, Inc. The AS carries the company's own corporate and operations network.
What it's used for
- Enterprise connectivity for a logistics business: order management, warehouse and fulfilment-centre systems, and the client-facing integrations a supply-chain outsourcer runs on behalf of consumer-electronics, software, and retail brands.
- RIS sees 4 announced IPv4 prefixes totalling 1,024 addresses, no IPv6, and 4 observed BGP neighbours. Four /24s and four upstreams is a small, deliberately multihomed end site. Nothing about the shape suggests hosting or transit; the AS exists to keep the company's own space reachable through more than one provider.
Notable
- All four prefixes —
216.245.20.0/24,216.245.40.0/24,216.245.47.0/24, and216.245.51.0/24— are registered to ModusLink Corporation itself under theMODUSLINKhandle. Holder and registrant agree throughout. The prefixes are non-contiguous slices of the same216.245.0.0range, which reads as blocks taken out of a larger allocation over time rather than as an assembled third-party inventory.
Interesting
- This one is genuinely old, which is not something to assume from a low AS number. ARIN records the assignment as registered in September 1998, with the record last updated in 2012. The holder has been renamed around it rather than replaced: the company began as College Marketing Group, became CMGI (the dot-com-era holding company behind Lycos and AltaVista), renamed to ModusLink Global Solutions in 2008, and became Steel Connect in 2018 with ModusLink surviving as the operating subsidiary. The AS number rode through all of it.

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 2026-10-14, 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: 442 networks and 1,772 prefixes, as published 2026-10-15. 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.
