About this network

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-ASN family registered in 1994 and inherited by Verizon in 2006; see also AS3369, AS3371, AS3372 and AS3373.
