About this network

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 netname ATTCH3 and 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.
