Abstract: Techniques are disclosed for auditing an IP address prefix that has been assigned to an entity as part of an administrator policy, to determine whether the assignment was implemented on the network. In an embodiment, associations between IP addresses and their assignment are stored in a database. IP addresses are read and semi-authoritative sources (e.g., DNS servers) are queried for information about the IP addresses. Information received in response to the query may be used to validate the IP address (e.g., in a network, all IP addresses used for VM instances will have a corresponding URL in a specific format).

Abstract: Methods and apparatus for bandwidth metering in large-scale networks are disclosed. Metadata for a network transmission involving a virtualized resource at a host of a provider network, including endpoint address information and a traffic metric, is determined at a metering component. The metadata is aggregated at another metering component and provided to a traffic classification node. The traffic classification node generates a categorized usage record for the network transmission, based at least in part on network topology information associated with the provider network. The categorized usage record is used to determine a billing amount for the network transmission.

Abstract: Disclosed are various embodiments to facilitate interactive experiences. Interactive content includes video content that is streamed to a client device, such as a set-top box. Complementary content is transmitted to a controller device, such as a tablet computing system and/or smartphone. Input obtained from the controller device can affect an update to the video content and/or complementary content.
