Unclassified ARIN
Summary
Verizon Business (MCI)
enterprise legacy
A legacy MCI autonomous system (MCI-ASN) held by Verizon Business, and the most
fragmented of the group: it originates over a hundred separate prefixes of Verizon's
inherited address space.
What it's used for
- Announcing many small Verizon Business allocations, largely carved out of the older MCI network blocks.
Notable
- Carrier address space, split into a large number of individual announcements rather than a few big aggregates, which is typical of long-lived enterprise and customer assignments accumulated over decades.
- One of the
MCI-ASNnumbers registered in 1994 and inherited by Verizon in 2006; its siblings are [AS3369](https://asn.ipinfo.app/AS3369), [AS3371](https://asn.ipinfo.app/AS3371), [AS3373](https://asn.ipinfo.app/AS3373) and [AS3374](https://asn.ipinfo.app/AS3374).
