AS15128 — COMWAVE-BGP-01

AS15128 announces 16 IPv4 prefixes covering 162,816 addresses and 6 IPv6 prefixes.

About this network

Two reverse names publish what look like the hardware addresses of the modem behind them.

What it's used for

• A telecom provider's network. Sixty-five IPv4 prefixes and forty-one IPv6 prefixes announced from Canada, over a hundred and sixty thousand addresses, with fifteen observed BGP neighbours.

Notable

• Two of ten answering addresses returned names under a cable carrier's domain in the form mta0018689aaf33-cm0018689aaf31.mta.net.cable.rogers.com, where each half is a twelve-character hexadecimal string and the two differ by two in the last digit.
• The rest answer under the operator's own domain, address-derived, with a service marker that is either tpia or dsl depending on the block.
• Two blocks registered to this holder carry the netname SHAW-CABLE, another carrier's name kept after the space changed hands.
• The IPv6 announcements descend from a /38 through a ladder of lengths down to individual /48 blocks, tiling one allocation.
• Most registrant fields append an abuse contact with a semicolon; one block omits it.

Interesting

• Hexadecimal identifiers in reverse DNS are a real disclosure. Two pieces of customer equipment are named by what appear to be their hardware addresses, publicly, keyed to an address, and they change only when the equipment does. That makes a subscriber's kit trackable across address changes by anyone sampling the zone.
• The two service markers split the network into distinct access types, a distinction that appears nowhere in the registry and only in DNS.
