Yes. Do NOT use IP adresses as identifiers. Just forget about it. People share connections, e.g. when they are in the same building or when they are using the same proxy. People use domestic/consumer internet connections that have dynamic IP addresses. Identifying people by their IP address is therefore stupid. If it is just to have a key to some data, you could try using a GUID. And check when you generate one that it doesn't already exist (though the chance is extremely small, it is not zero). Or just use some serial number like everyone else does ;) It may look boring to make files like order0001, order0002 etc. But it works. Any reason you are not storing your orders in a database?
