AS11757 WHIRLPOOL-ASN

WHIRLPOOL-ASN really is Whirlpool Corporation, the home-appliance manufacturer, registered at 2000 North M-63 in Benton Harbor, Michigan — the company's global headquarters. It is a large enterprise AS carrying Whirlpool's own corporate network.

What it's used for

Corporate enterprise multihoming at manufacturer scale. RIS shows 14 IPv4 prefixes covering 68,608 addresses and no IPv6, against just 4 observed BGP neighbours. That combination is the point: a network announcing 68k addresses with only four peers is not a carrier — a wholesale transit AS of that size would peer with hundreds. It is one company with a lot of address space and a handful of upstreams.

The inventory is entirely self-held. The bulk is the legacy 158.52.0.0/16 (65,536 addresses), with three /22s out of 159.155.0.0/16 making up the rest; the remaining announcements are /23 and /24 more-specifics carved from those two blocks, which is why the address count lands exactly on 68,608 rather than double-counting. Every prefix registers to Whirlpool Corporation at the Benton Harbor address, under the netnames WHR and WHR2-COM.

Notable

Whirlpool is the exception in a neighbourhood full of reissues. Its immediate siblings in this range were handed to their current holders in 2014 and 2023, but ARIN records AS11757 as registered in December 1998, and the 158.52.0.0/16 network object dates to February 1992 — a genuine legacy Class B still held and announced by its original organisation. The org handle's -Z suffix is an ARIN legacy-cleanup artifact, not a sign of reassignment.

Interesting

No PTRs came back on the 20 addresses sampled. That is a sample, not a finding, and supports no conclusion about how the space is used internally.
