Summary
Verizon Business (MCI)
enterprise legacy
A legacy MCI autonomous system (MCI-ASN) held by Verizon Business, originating a
small amount of the address space Verizon inherited from MCI.
What it's used for
- Announcing a couple of long-standing blocks within the Verizon Business network.
Notable
- Carrier address space, small enough that it functions as a corner of Verizon's network rather than a service platform in its own right.
- Part of the
MCI-ASNfamily registered in 1994 and inherited by Verizon in 2006; see also [AS3369](https://asn.ipinfo.app/AS3369), [AS3371](https://asn.ipinfo.app/AS3371), [AS3372](https://asn.ipinfo.app/AS3372) and [AS3373](https://asn.ipinfo.app/AS3373).
