Autonomous system
AS6534 OCEANIC-CABLE - Charter Communications Inc
Unclassified ARIN
Summary
Oceanic Cable (Charter Communications)
isp legacy
OCEANIC-CABLE is the legacy autonomous system of Oceanic Cable, the dominant cable operator in Hawaii. Oceanic passed through Time Warner Cable and is today part of Charter Communications, which holds the ARIN registration.
What it's used for
- Network infrastructure rather than subscriber access. The AS originates only a couple of prefixes, and their reverse DNS resolves to Charter's infrastructure domain (
inf.spectrum.com) and to device-style names underhicv.net— hostnames likehnllhiuf01wandmilnhiqfx02encode Honolulu and Mililani site codes. - Hawaii's residential Spectrum subscribers are numbered out of Charter's much larger nationwide autonomous systems, not this one.
Notable
- Do not read this AS as an eyeball network just because its parent is a cable ISP. What it actually announces is a small block of routers and platform addressing; the consumer address pools live elsewhere in Charter's estate.
- The
hicvlabel is a fossil of Hawaii Cablevision, the naming that predates both the Time Warner and Charter eras. Acquisition rarely rewrites rDNS.
Interesting
- The ASN is a genuine 1996 ARIN registration, from the period when a state's incumbent cable operator was still an independent regional company. The number survived two corporate absorptions while the brand on the truck changed twice.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
