Summary

Astound (RCN)

United States · AI-generated

isp residential eyeball cable fiber

AS6079 is the legacy RCN network, now part of Astound Broadband — a US residential cable and fibre ISP built from RCN, Grande, Wave and enTouch.

What it's used for

  • Cable and fibre home internet for consumers in metros across the US, including parts of the Northeast, Chicago, DC, Texas and the West Coast.

Notable

  • A large "eyeball" network: addresses here are home connections, commonly behind carrier-grade NAT, not servers.
  • Astound is one of the larger US "overbuilder" cable operators, competing head-to-head with incumbents rather than holding a monopoly franchise.

Interesting

  • The AS6079 origin dates to RCN, one of the earliest competitive fibre/cable overbuilders, before the Astound consolidation of RCN, Grande and Wave.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
