Summary
Michigan Broadband
isp eyeball legacy
MICHIGAN-BROADBAND is registered to Alpha Enterprises Limited, Inc. and operates as Michigan Broadband, a rural telephone and broadband group in Michigan. Its address blocks are registered to Upper Peninsula Telephone Company in Carney, Michigan.
What it's used for
- Rural fixed broadband in Michigan, largely in the Upper Peninsula and neighbouring rural exchanges, alongside the incumbent telephone service those companies were built on.
Notable
- An eyeball network at small scale: the announced space is a scatter of
/24s in the 67.22 and 64.29 ranges, with the 67.22 blocks explicitly named for Michigan Broadband's high-speed data service. - The corporate name on the ASN (Alpha Enterprises Limited) does not match the service brand, which is common for rural telco groups where an operating company holds the registry records for affiliated exchanges.
Interesting
- Serving the Upper Peninsula means running plant across some of the least dense territory in the Midwest, which is why the network appears as many small prefixes rather than one large aggregate.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
