residential business cable access

CHARTER-22974-MICHIGAN-DETROIT-C3 is operated by Charter Communications LLC.

What it's used for

  • The address space carries residential and business broadband traffic, evidenced by reverse DNS entries such as syn-192-062-250-000.res.spectrum.com and syn-076-058-006-128.biz.spectrum.com.
  • With 3840 IPv4 addresses and 5 IPv6 prefixes announced against 36 observed neighbours, the ratio indicates an access network providing connectivity to end-users rather than a transit provider.

Notable

  • Registrants include Charter Communications LLC, Charter Communications Inc, NMHM Hotels, Ionia County ISD, La-Z-Boy Incorporated, and NT Consulting Solutions, LLC, reflecting a mix of direct holdings and leased or customer-specific blocks.

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 1,783 prefixes, as published 2026-10-17. 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.
