About this network

ATT-CH-0D is one of AT&T Global Network Services' per-country ASNs in Europe, registered to AT&T Global Network Services Nederland B.V. in The Hague and administered from AT&T's Swiss operation.

What it's used for

• Managed network services for AT&T's enterprise customers, the business descended from the old AT&T WorldNet and Managed Internet Service (MIS) offering that AT&T acquired with IBM Global Network.
• A single /24 is announced, drawn from a larger AT&T Global Network Services allocation held by the Dutch entity.

Notable

• AT&T Global Network Services ran a family of small, country-scoped ASNs across Europe rather than a single regional AS. The -CH- in the handle marks this one as the Swiss node, and the administrative contact is AT&T's Swiss network admin.
• It is a corporate managed-services network, not a consumer ISP: there are no subscriber-style reverse DNS pools in the announced space.
