Summary
Charter (legacy Bright House, Florida)
isp residential eyeball cable
A Charter Communications network inherited from Bright House Networks, now part of the Spectrum broadband footprint in Florida.
What it's used for
- Cable home internet for residential Spectrum subscribers, concentrated in central Florida (the Tampa/Orlando area).
Notable
- An "eyeball" network: addresses here are home connections, commonly behind carrier-grade NAT, not servers.
- Bright House was acquired by Charter in 2016 and folded into Spectrum; this ASN now rolls up to Charter alongside the legacy Time Warner Cable networks such as AS11351.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
