About this network

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 65.228.0.0/16 and 65.229.0.0/16, 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.
