VpcPublicIp

The acquire, attach, detach or release job driving this address right now; null when none is. Recomputed on every read rather than remembered from the 202 that started the work, so ANY reader picks the job up — a second device, a cleared browser, another user in the same tenant — and not only the browser that issued the request.

The attached machine's name, resolved when the list is read. Null on a held address, and null when the binding names no live machine — a VM row can be tombstoned before its addresses are released, and the field is never a stale name or the id echoed back. Always present.

True while the address is allocated but bound to no machine
