Summary

Charter Communications

United States of America · AI-generated

residential cable spectrum voip

The AS handle CHARTER-19115-DC is held by Charter Communications LLC.

What it's used for

  • The address space carries residential broadband and voice services, evidenced by reverse DNS names such as syn-098-008-200-000.inf.spectrum.com and syn-016-014-242-000.voip.spectrum.com.
  • With 40448 IPv4 addresses announced against only 7 observed neighbours, the ratio indicates a large access or eyeball network rather than a transit provider.

Notable

  • Registrants are consistent with the announcer, listing both Charter Communications Inc and Charter Communications LLC across the largest prefixes.
  • Charter Communications acquired Time Warner Cable in 2016, which explains the presence of legacy netnames like RRNY and ROADRUNNER-2-MIDSOUTH alongside newer CC04 designations.
  • The inventory includes 30 IPv4 prefixes and 19 IPv6 prefixes, with the largest block being 98.8.192.0/19.

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 1,772 prefixes, as published 2026-10-15. 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.
