Summary
Charter Communications (formerly Time Warner Cable)
isp legacy
TWC-3456-IT is a legacy Time Warner Cable autonomous system, now held by
Charter Communications, which acquired TWC in 2016 and operates the combined
network under the Spectrum brand.
What it's used for
- Cable ISP address space inherited from Time Warner Cable, folded into Charter's network after the merger.
- Consumer and business broadband service rather than hosting or transit.
Notable
- This is eyeball address space: the hosts behind it are largely residential subscribers, so it behaves like a consumer ISP range.
- Charter holds a long tail of AS numbers absorbed from Time Warner Cable, Bright House, and Charter's own history. The
TWC-handles are the clearest fingerprint of which lineage a given number came from.
Interesting
- The AS number outlives the brand. Time Warner Cable no longer exists as a company, but its registry handles keep showing up in routing data years later.
