To be honest we don't do usage billing so I've never used it. I'd like to think it is since it uses a verification between the collector and source.

I'm not sure that IPDR is used much outside of the HFC world though. IPDR was my first thought as an alternative to SNMP. Is its accuracy comparable? It’s been included into TR-069, so it’s theoretically available to telcos, too. And usage-based billing is part of it’s purpose. Not sure I’d want to use NetFlow/IPFIX, since by nature it tracks flows, not bits, and I don’t want to record flows. But I’d be interested in hearing others’ experience.
