AS11285 KW-CORPORATION

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.
