Summary
Charter / Spectrum
isp cable eyeball
Charter Communications (CHARTER-20115) — the US cable operator that sells home internet under the Spectrum brand.
What it's used for
- Cable home and business broadband across much of the United States.
Notable
- One of the two largest US cable ISPs (with Comcast); a major "eyeball" network of residential subscribers.
- Grew massively by acquiring Time Warner Cable and Bright House in 2016.
Interesting
- "Spectrum" is the retail brand; the underlying company and network are Charter, which is why lookups show Charter rather than Spectrum.

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: 440 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.
| Prefix | Advisory | Published |
|---|---|---|

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