Summary

Charter Communications Inc

United States · AI-generated

isp telecom media

The AS handle contains its own AS number, and every reverse name pads each octet to three figures so the labels sort correctly as text.

What it's used for

  • A cable operator's regional network. 18,432 addresses across eight IPv4 prefixes, with a single observed BGP neighbour and no IPv6 announced.

Notable

  • The handle is TWC-14065-COUDERSPORT, naming a predecessor company, the AS number itself and a town.
  • All eight blocks are registered to Charter Communications Inc, under four different netnames: RRMA, RR, ROAD-RUNNER-HOLDCO-LLC and COUDERSPORTBB-3.
  • All eighteen sampled addresses returned a name, every one of the form syn-075-180-136-000.inf.spectrum.com, with a variant ending res.spectrum.com.

Interesting

  • Zero-padding each octet to three digits means the names sort in address order in any plain text tool. Nobody does this by accident; it is a scheme designed for people reading log files rather than for people reading hostnames.
  • Three of the four netnames are abbreviations of a brand retired years ago, one of them still carrying its holding company's legal suffix. The registry preserves the corporate history that the marketing does not.
  • Putting the AS number inside the handle makes the record self-referential, which is useful exactly once: when a carrier holds dozens of small regional AS numbers and needs to tell them apart.
  • One neighbour on a cable network this size means it is a leaf of a much larger backbone. The AS exists to keep an acquired system administratively separate, not to give it independent connectivity.

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: 440 networks and 1,773 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.
