Summary

Charter Communications

United States of America · AI-generated

cable residential spectrum access

CHARTER-23200-INDIANA-C3 is operated by Charter Communications LLC.

What it's used for

  • The address space carries residential and business customer traffic, evidenced by reverse DNS entries such as syn-159-056-145-000.inf.spectrum.com and syn-159-056-146-254.biz.spectrum.com.
  • The AS announces 1024 IPv4 addresses and 4 IPv6 prefixes with only 2 observed neighbours, a ratio characteristic of an access or eyeball network rather than a transit provider.

Notable

  • The RDAP registrant for the announced prefix 159.56.144.0/22 is Charter Communications LLC, matching the AS holder.
  • The inventory consists of a single IPv4 prefix (159.56.144.0/22) and four IPv6 prefixes, representing a small, specific slice of the operator's total address space.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
