About this network

Corporate ASN (PHONAK-LLC) of Phonak, LLC, the US arm of the Phonak hearing-aid business, part of the Swiss Sonova Group.

What it's used for

• Corporate networking for Phonak's United States operations: offices, business systems, and internet-facing corporate services.
• Announces only a single small block (a /24), so the footprint is deliberately tiny.

Notable

• Enterprise address space: it serves one company's own staff and systems, not subscribers or hosted customers.
• A hearing-technology manufacturer holding its own AS number is unusual. Most companies of this size sit behind a provider's addresses rather than running BGP themselves.

Interesting

• The whole allocation is 256 addresses, one of the smallest footprints you will find on a low-numbered ARIN ASN. The AS number is the notable part, not the size of the network behind it.
