Summary
AT&T (EasyLink)
enterprise legacy
An AT&T autonomous system registered with ARIN in 1995 and held today by
AT&T Enterprises, LLC, under the legacy EASYLINK4 handle.
What it's used for
- Announcing a handful of AT&T prefixes, mostly out of
204.127.0.0/16, in support of AT&T-run services. - A small, special-purpose ASN — not one of AT&T's major transit or consumer broadband networks.
Notable
- The address space is corporate rather than residential: these routes back AT&T's own service infrastructure, not home subscriber pools.
- Sibling of [AS4466](https://asn.ipinfo.app/AS4466), which carries the matching
EASYLINK2handle from the same registration batch.
Interesting
- The EasyLink name traces back to the electronic messaging, fax, and telex business AT&T bought from Western Union in 1990. The product line eventually moved on to other companies; the AS handle did not.
