Unclassified ARIN
Summary
K W Corporation, Inc.
enterprise legacy
KW-CORPORATION is a single-prefix network run by K W Corporation, Inc., a small IT services and managed-service company registered at 307 W Grand River Ave, Fowlerville, Michigan. RIS sees exactly one route: 198.61.57.0/24, 256 addresses, no IPv6, 2 observed neighbours.
What it's used for
The company's own infrastructure and the addresses it hands to the customers it supports. Two clues carry this. The prefix is registered to KW-WAN (org: K W Corporation, Inc.) — the netname literally describes a wide-area network, not a datacentre. And the sampled reverse DNS is first-party and self-consistent: kwns2.kw-corp.com is a name server, while s-198-61-57-133.unassigned.static.kw-corp.com is a templated static-assignment name with the "unassigned" slot still in it. That is the rDNS of an operator that carves a /24 into static allocations, which fits a managed-IT provider giving business clients fixed addresses far better than it fits either a hosting farm or a residential pool.
Notable
Two observed neighbours and a single /24 is about as small as a routed network gets. The AS exists for one reason: to multi-home 256 addresses across two upstreams so a business network stays reachable if one link fails. There is nothing here resembling leased address space — one prefix, one RIR, registered to the holder, wearing the holder's own rDNS.
Interesting
The AS number is misleadingly low. ARIN's registry shows AS11285 registered to K W Corporation on 2 October 2013 and last changed later that month, so this is a recycled number, not an early-internet allocation. Treat the four-digit prefix of the AS number as no evidence of age at all here; the registry date is the only thing that speaks to it.

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: 453 networks and 1,846 prefixes, as published 2026-11-11. 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.
