Unclassified ARIN
Summary
AT&T Enterprises, LLC
enterprise legacy
ATTIS-ASN3423 is held by AT&T Enterprises, LLC, the entity that holds
AT&T's ARIN registrations. It is one of many AT&T AS numbers, and a small one:
its announced footprint is a few thousand IPv4 addresses.
What it's used for
- Part of AT&T's wider ASN estate, alongside its main backbone AS [AS7018](https://asn.ipinfo.app/AS7018).
- A limited set of prefixes rather than a broad consumer or backbone network, which points to internal or specific-service use rather than mass eyeball broadband.
Notable
- Large carriers accumulate dozens of AS numbers through decades of mergers, acquisitions, and separate business units. Not all of them carry meaningful traffic volume.
- The
ATTIShandle and the low number both date the registration to the mid 1990s, well before AT&T's modern network took its present shape.
