AS12387 — TON TON Total optical Networks AG

AS12387 announces 2 IPv4 prefixes covering 9,216 addresses and 1 IPv6 prefixes.

About this network

A Swiss provider with far more peering than its size would suggest.

What it's used for

• Business connectivity and transit. 9,216 addresses in two IPv4 prefixes, one IPv6 /32, 144 observed BGP neighbours.

Notable

• 144 neighbours against 9,216 addresses. That ratio marks a network whose business is carrying other people's traffic rather than serving its own customers' addresses.
• The /19 is the provider's own, CH-TON-NET-20070207. The /22 is not: 195.4.176.0/22 is WORTMANN-AG-NET, registered to terra CLOUD network management.
• Addresses in the provider's own block answer positionally as 77-237-200-0.ton-net.com.

Interesting

• Switzerland is a good place to be a network with many peers and few customers. Zurich and Geneva sit between the German, French and Italian markets, and a Swiss AS that shows up at the exchange points can sell reach in three directions at once. The address count is incidental to that business; the neighbour count is the product.
• The second block belongs to a German hardware manufacturer's cloud division, announced from a Swiss AS. Providers regularly carry a customer's own registered space this way, and the netname is the only trace of whose it is.
