Autonomous system
AS3373 MCI-ASN
Unclassified ARIN
Summary
Verizon Business (MCI)
enterprise legacy
A legacy MCI autonomous system (MCI-ASN) held by Verizon Business. It is one of
the quietest of the group, originating a single block from Verizon's inherited
address space.
What it's used for
- Announcing one UUNET-era customer allocation within the Verizon Business network.
Notable
- Carrier-held address space rather than an independent organisation's network. A single-prefix ASN like this usually reflects a narrow, long-standing assignment rather than an active service platform.
- Registered in 1994 as part of the
MCI-ASNfamily and carried into Verizon with the 2006 MCI acquisition, alongside [AS3369](https://asn.ipinfo.app/AS3369), [AS3371](https://asn.ipinfo.app/AS3371), [AS3372](https://asn.ipinfo.app/AS3372) and [AS3374](https://asn.ipinfo.app/AS3374).
