Autonomous System 7016 (CCCH-3, for Comcast Cable Communications Holdings) is a Comcast network used for its business services, distinct from the residential cable network.

What it's used for

  • Originating static-IP and BGP-routed blocks assigned to Comcast Business customers, plus a large number of IPv6 /48 delegations to those same customers.
  • Reverse DNS on the space that resolves lands on …-ip-static.hfc.comcastbusiness.net — static assignments over Comcast's hybrid fibre-coax plant.

Notable

  • Not Comcast's eyeball network. Comcast's mass-market residential broadband is AS7922; AS7016 carries the commercial side, so IPs here belong to offices, shops and business sites rather than homes.
  • The IPv6 footprint dwarfs the IPv4 one: hundreds of customer /48s out of Comcast's 2001:559::/32 versus a modest number of small IPv4 blocks.

Interesting

  • A good example of why an AS should be read on its own terms: sharing an owner with one of the largest consumer ISPs in the world says nothing about what this AS number actually carries.

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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
