Summary
Charter Communications (Spectrum)
isp residential eyeball cable
A Charter Communications regional network (CHARTER-22516-CENTRAL-CA-C3), carrying Spectrum consumer broadband in Charter's central-California footprint.
What it's used for
- Cable and fibre home internet for Spectrum subscribers in the region.
Notable
- A large "eyeball" network — addresses here are home connections, commonly behind carrier-grade NAT, not servers.
- Charter runs many regional ASNs that all roll up to the Spectrum network. The post-merger primary is AS20115; the legacy Time Warner Cable and Bright House blocks include AS20001, AS10796, AS11351, AS11427, AS12271, and AS33363.
Interesting
- The RIR handle encodes the service area —
CENTRAL-CA— which is why an IP here geolocates to central California rather than to Charter's Connecticut headquarters.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
1 IC3 indicators addresses in this network appear in FBI IC3 cybersecurity advisories.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
