Summary
AcenTek
isp legacy
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.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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 1,782 prefixes, as published 2026-10-16. 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.
