Summary
AT&T Data Communications Services
enterprise legacy
INS-AS is an AT&T network, registered to AT&T Data Communications Services and today held under AT&T Enterprises, LLC.
What it's used for
- Enterprise and data-communications networking within AT&T's US operations.
Notable
- A genuinely early allocation, registered with ARIN in 1993, so the low AS number does reflect an early-internet assignment rather than a modern reissue.
