AS11904 ATOM-MI-53-198

ATOM-MI-53-198 is AcenTek, a rural telephone and broadband cooperative descended from Ace Telephone of Houston, Minnesota, which serves subscribers across parts of Minnesota, Iowa and Michigan. The handle decodes the way most handles in this range do — as an internal label, here the company's Michigan operating arm, and ARIN registers the ASN to an address in Mesick, Michigan.

What it's used for

This is an eyeball access network. RIS sees 32 IPv4 prefixes carrying 19,456 addresses, 3 IPv6 prefixes, and only 6 observed neighbours — a large-ish address pool reached through very few upstreams, which is the subscriber-ISP shape rather than the transit-carrier one (a wholesale carrier would show peers by the hundred). The announcements deaggregate heavily inside a few parent blocks (24.204.160.0/19, 107.155.176.0/20, 209.25.240.0/20), all registered to AcenTek itself.

The reverse DNS confirms what the space carries: names like ip-107-155-176-5-static.hsip.as19531.net, host5.maxim.net and static-242-005.allcom.net are subscriber-facing static-IP naming from the company and from networks it absorbed. "hsip" is simply high-speed internet product naming — an access technology label, not a customer type. Multiple rDNS suffixes under one origin AS is exactly what a decades-long history of buying small local telephone companies leaves behind.

Notable

The ASN dates to 1999 and the underlying business to a 1950s farmer-founded rural telephone co-op; the fragmented rDNS is the visible sediment of its acquisitions.
