AS8238 ATT-CH-0C AT&T Global Network Services Nederland B.V.
Unclassified RIPE
Summary
AT&T Global Network Services (EMEA managed customer)
enterprise legacy
A single-prefix Autonomous System operated by AT&T Global Network Services Nederland B.V., the European arm of AT&T's managed-network business (the former IBM Global Network). The registry describes it simply as AT&T VAS EMEA with an internal reference code, and the ATT-CH-0C handle points at a Swiss site.
What it's used for
- Announcing one /24 out of AT&T Global Network Services' own European allocation, on behalf of a managed enterprise customer or service platform.
- Its whole routing policy is a single upstream: it imports from and exports to AS2686 (AT&T's EMEA network) and nothing else. There are no peers and no downstream networks.
Notable
- Managed-service space, not consumer or hosting. AT&T Global Network Services numbers enterprise customer sites and value-added-service platforms out of its own blocks and announces them from small dedicated ASNs like this one; the addresses sit behind corporate connectivity, not a public service.
- No reverse DNS is published on the /24, which is typical for a managed enterprise range.
- The registry gives an internal designator rather than a customer name, so no further identification is honest here. Do not infer AT&T's US consumer or mobile business from the brand: this is the enterprise networking arm.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 448 networks and 1,851 prefixes, as published 2026-11-03. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
