Our Express route is currently only utilized for private peering. We do not own a public IPv4 address space but would like to be able to utilize peering with Microsoft over our express route. From my readings it appeared that you have to utilize public ip's in the peering and you have to be the owners of those IPs. Is there any other way of setting up peering with MS? (acquiring the /30 from Microsoft perhaps?) Or an IP provider who would lease us a /30?
