Autonomous system
AS3369 MCI-ASN
Unclassified ARIN
Summary
Verizon Business (MCI)
enterprise legacy
One of Verizon Business's legacy MCI autonomous systems (MCI-ASN), used to
originate a slice of the address space Verizon inherited when it acquired MCI in
2006.
What it's used for
- Announcing Verizon Business network and customer blocks, including ranges whose registry records still carry old UUNET names.
Notable
- Carrier address space rather than a single organisation's network: the prefixes behind it are allocated out to Verizon Business services and customers, so addresses here are typically business or infrastructure rather than eyeball.
- Verizon runs a whole family of
MCI-ASNnumbers in this range — see [AS3371](https://asn.ipinfo.app/AS3371), [AS3372](https://asn.ipinfo.app/AS3372), [AS3373](https://asn.ipinfo.app/AS3373) and [AS3374](https://asn.ipinfo.app/AS3374) — all registered together in 1994 and all still held under the same organisation.
