Internet Protocol Detail Record

In telecommunications, an IP Detail Record (IPDR) provides information about Internet Protocol (IP)-based service usage and other activities that can be used by operations support systems (OSSes) and business support systems (BSSes). The content of the IPDR is determined by the service provider, network/service element vendor, or any other community of users with authority for specifying the particulars of IP-based services in a given context.
