Summary
AT&T Technical Services Company
enterprise legacy
ATS-NET, registered to AT&T Technical Services Company, Inc., an AT&T
subsidiary providing technical and systems services to government and enterprise
customers.
What it's used for
- Corporate networking for the subsidiary and the programs it supports. The allocation is modest (about 3,840 IPv4 addresses), consistent with an internal enterprise network rather than a carrier network.
Notable
- Despite the AT&T name, this is not one of AT&T's large consumer or backbone ASNs — those live elsewhere in the AT&T family. This is a separate, subsidiary-scale registration.
- Enterprise address space, not eyeball or hosting.
Interesting
- The ARIN record dates to 1994, when large corporations were registering distinct AS numbers per business unit rather than consolidating under one.
