Summary
Charter (legacy Bright House Networks)
isp residential eyeball cable
Charter Communications (BRIGHT-HOUSE-NETWORKS) — a Charter ASN carrying legacy Bright House Networks cable IP space, now part of Spectrum.
What it's used for
- Cable home internet for US residential customers, primarily in Florida and other former Bright House markets.
Notable
- An "eyeball" network: addresses here are US home connections, commonly behind carrier-grade NAT, not servers.
- Charter acquired Bright House (and Time Warner Cable) in 2016; these all roll up to the Spectrum-branded network.
Interesting
- Charter runs several ASNs from its acquisitions — see the primary Charter network at AS20115.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
