Summary
AT&T Global Network Services (managed hosting)
hosting legacy
ATT-ASIAPACIDC-SNG1-AS is an AT&T managed-hosting autonomous system. The registry remark names it "AT&T Webhosting Singapore IDC", while the organisation holding it today is AT&T Global Network Services Nederland B.V.
What it's used for
- Managed hosting and internet data-centre services for AT&T's enterprise customers. The registered technical contacts are AT&T's Managed Hosting Operations group.
- The AS is small and specific. It is one of a family of per-site AT&T hosting ASNs rather than any part of AT&T's carrier backbone.
Notable
- The handle and the routing no longer agree, and the routing is the honest one. The single prefix announced today,
194.11.236.0/23, is registered with netnameATTCH3and a Brüttisellen, Switzerland address, not Singapore. The Singapore IDC naming appears to be a fossil of the AS's original purpose. - Because the announced footprint is one /23 with no reverse DNS, what the space currently serves cannot be pinned down from public data with confidence.
Interesting
- The maintainer list on this object is a small archaeology of AT&T's network acquisitions, carrying maintainers for several unrelated AS numbers alongside this one.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
