About this network

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.
