AS4445 CWI-AS

CWI-AS is registered to Vodafone Americas, the US-registered arm of the Vodafone

group, from an address in New York. The handle predates the current registration

and says nothing useful about the network's present use.

What it's used for

• A small Vodafone group network rather than a consumer-facing one. It announces only a few /24s, and those prefixes are registered to Vodafone entities in the UK and Germany — a pattern that points at internal carrier infrastructure, not customer address space.
• Routing data shows a stub: a couple of peers and a single upstream, which is not the shape of an ISP serving end users.

Notable

• Carrier infrastructure address space. An IP here is far more likely to be Vodafone's own systems than a Vodafone mobile subscriber.
• The ARIN organisation record sits in New York while the address space it announces sits in the RIPE region — a reminder that the registry holding an ASN and the registry holding its prefixes need not be the same.

Interesting

• Some routing databases annotate this network as a GRX (GPRS Roaming Exchange) network — the kind of interconnect that lets a roaming subscriber's traffic reach their home operator. That is a community annotation rather than anything the registry states, so treat it as a hint rather than a fact.
