Summary
AT&T Enterprises, LLC
enterprise isp legacy
ATTIS-ASN4185 is registered to AT&T Enterprises, LLC. The handle reflects its
origin as an AT&T Internet Services network, and it is one of many AS numbers
AT&T operates.
What it's used for
- Carrying enterprise and managed-service customer networks rather than acting as one of AT&T's main backbone or consumer-broadband ASNs.
- The announced prefixes are a mix of slices out of AT&T's own
12.0.0.0/8and several customer-sized/16blocks, which is the shape of dedicated business internet access and managed hosting rather than a residential eyeball pool.
Notable
- AT&T runs a large family of AS numbers; this one is a secondary member of that family, so its footprint (a couple hundred thousand addresses) is far smaller than AT&T's flagship networks.
- The organization record was updated in a recent corporate reorganization, but the AS number itself has been AT&T-side since the mid-1990s. The low number is genuine, not a reissue to a new holder.
