Summary

Charter Communications (legacy Time Warner Cable)

United States · AI-generated

infrastructure cable legacy

TWC-8052-PEAKVIEW is a legacy Time Warner Cable handle now held by Charter Communications. Despite the cable-ISP parentage, this AS carries network infrastructure, not subscribers.

What it's used for

  • Charter's own operational equipment in the Denver, Colorado metro. Every sampled address resolves either to syn-IP-ADDR.inf.spectrum.com — Charter's infrastructure reverse-DNS zone, distinct from the res and biz zones used for customers — or to named devices under netops.charter.com and rig.charter.com with dnvr (Denver) site codes, including video headend switches and core routers.

Notable

  • Roughly 15,000 addresses across ~21 prefixes, with a single observed BGP peer. There is no subscriber space here at all: not one sampled IP fell in the res.spectrum.com or biz.spectrum.com zones.
  • Because of that, an IP in AS8052 should not be read as a cable customer. Charter and legacy Time Warner Cable eyeball addresses live on other Autonomous Systems.
  • Left deliberately unclassified rather than filed under any user-facing kind — an infrastructure-only AS has no honest bucket.

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: 436 networks and 1,771 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

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.
