About this network

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.
