Gaurav, "Ideally, when we search by Id, then exception should be thrown and when We expect by passing account/domainid/projectid/networkid etc, then Noneshould be returned. Do all List APIs follow a similar guideline?²
Yes, all of CS APIs follow this behavior. If non-existing Id is passed in, then the error is thrown by the DB Id validator. In case of public ip address its different, and let me explain why. When the ip gets disassociated, it doesn¹t get deleted. It¹s just marked as non-allocated, and left in the DB so next associateIpAddress can pick it up. Therefore you don¹t see any exception when requesting the ip by id. Why empty list is returned then? Because by default, listPublicIpAddresses returns allocated ips only. If you want to see free ips as well, you have to pass ³allocatedOnly=false² to the call. Hope it answers your question. -Alena.
