residential wireless isp michigan

DMCI-BROADBAND is operated by DMCI Broadband, LLC.

What it's used for

  • The address space carries residential wireless broadband traffic, evidenced by netnames DMCIBB-CORE and DMCIBB registered to DMCI Broadband, LLC.
  • The AS announces 5,632 IPv4 addresses across 3 prefixes with only 1 observed neighbour, a ratio characteristic of an access network serving local subscribers rather than a transit provider.
  • Traffic consists of subscriber internet access for households in the Reading, Michigan area, where the company provides wireless broadband services.

Notable

  • Registrants for the two largest prefixes (204.106.240.0/20 and 104.249.148.0/22) align with the announcer, while the smallest prefix 38.57.190.0/23 is registered to Cogent Communications, LLC under netname COGENT-A.
  • The address inventory is compact, consisting of one /20, one /22, and one /23 block, all located in the United States.

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: 442 networks and 1,778 prefixes, as published 2026-10-20. 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.
