Summary
Cellco Partnership (Verizon)
enterprise legacy
CELLCO-PART — Cellco Partnership, the legal entity that does business as Verizon Wireless. The ARIN organisation on the record today is Verizon Business (MCICS, Ashburn, Virginia).
What it's used for
- Announces roughly a hundred small prefixes drawn from legacy UUNET blocks in
65.228.0.0/16and65.229.0.0/16, address space that came into Verizon through the MCI/UUNET side of the business. - The sampled addresses carry no reverse DNS, so the traffic they serve is not visible from the outside; this is not the consumer mobile eyeball network.
Notable
- Verizon's mobile subscriber traffic largely rides other ASNs — this one is a separate, much smaller Cellco/Verizon Business network, so it should not be read as "Verizon Wireless customers".
- A reminder that a carrier's ASNs are not interchangeable: the same corporate parent runs backbone, enterprise and eyeball networks under different numbers.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
