Summary

MTC Broadband

United States of America · AI-generated

residential broadband isp

MTC-BROADBAND is the AS handle for MTC Broadband, Inc.

What it's used for

  • The space carries residential broadband access, evidenced by reverse DNS entries like cm-74-115-74-0.mville.mtcbroadband.net and netnames such as MTC-BROADBAND.
  • The AS announces 11,008 IPv4 addresses across 21 prefixes with only 5 observed neighbours, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

  • Registrants are mixed; while most prefixes are registered to MTC Broadband, Inc., several blocks including 38.76.80.0/22 and 38.57.154.0/23 are registered to Cogent Communications, LLC under the netname COGENT-A.
  • The address inventory is fragmented, consisting of a mix of /21, /22, /23, and /24 blocks, with no IPv6 prefixes in the inventory.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
