Hi,
The company requesting the IPv6 PI is a hosting company providing software as a service solution for its customers. All the infrastructure (servers, routers...) is owned by them. For security reasons, they chose to isolate each of their customers on a separate VLAN. Their customer don't have administrative access to the servers and just uses the software hosted on them for their CRM, extranet or other corporate applications.
Would you consider this to be the exact same case as an ISP assigning an IP to a customer's CPE?
No. This all sounds like their own infrastructure/network/equipment. That they run software for customers, and that they choose a certain numbering plan shouldn't make a difference here. When they provide network services to their customer it starts to become more complicated, but this doesn't sound like a problem for IPv6 PI space to me. (based on the given information of course. I'm not trying to tell an IPRA what to do... They might have based their evaluation on different information) But the way you describe it it does not sound like they assign address space to other organizations. It sounds like they assign address space to parts of their own server farm. But this is my personal interpretation of the current policy. If someone disagrees with this, please speak up! Sander
