About this network

Every netname is a bare number, and none of the numbers relate to the addresses.

What it's used for

• A large consumer provider. Seventy IPv4 prefixes announced from Brazil, no IPv6, and a hundred and forty-five thousand addresses.

Notable

• The netnames are numbers with no letters at all: 33135, 49455, 480587, 4514, 9693. They are of different lengths and none of them encodes the block they label.
• Blocks in unrelated ranges share a netname, so the number groups assignments by something the registry does not otherwise show.
• The registrant is identical on every block and contains a full stop inside the company name, which the AS handle repeats verbatim.
• Eighteen addresses were queried for reverse DNS and none returned a name.
• Only one BGP neighbour is observed for the whole network.

Interesting

• A purely numeric netname is the least useful label a registry entry can carry. It is almost certainly a ticket or customer identifier from an internal system, exported into a public field where the system that gives it meaning is not available. Two blocks sharing the number tell you they were requested together and nothing more.
• One observed neighbour for a hundred and forty-five thousand addresses says the announcements reach the collectors through a single path, which is a measurement artefact as much as a topology fact.
• No reverse names at all across a consumer network of this size means subscriber addresses carry no region or product hint, which is unusual for a provider this large.
