cable residential business spectrum

CHARTER-23132-SOUTHERN-NEW-ENGLAND-C3 is held by Charter Communications LLC.

What it's used for

  • The address space carries residential and business subscriber traffic, evidenced by reverse DNS entries like syn-159-056-138-000.biz.spectrum.com and syn-076-058-002-128.biz.spectrum.com.
  • The AS announces 3072 IPv4 addresses across 4 prefixes and 6 IPv6 prefixes, with only 7 observed neighbours, indicating a local access network rather than a transit provider.

Notable

  • Registrants include Charter Communications LLC, Charter Communications Inc, PCNet, Inc., and IPG Photonics, with netnames such as CC04 and RRPRI.
  • The address inventory is a mix of legacy and acquired blocks, including space originally registered to PCNet and IPG Photonics, now integrated into the Spectrum network.

Reputation

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.
