Abstract
Methods, apparatus, computer-storage media, mechanisms, and means associated therewith are used to limit network device resources based on the identification of the Internet Protocol version 6 (IPv6) originating entity (e.g., subscriber of a network carrier). As an IPv6 originating entity will typically be assigned 2or more valid IPv6 addresses, the originating entity may send packets with a source address of any of these valid IPv6 addresses and still be compliant with Internet standards and/or other specifications (e.g., RFCs). By determining the originating entity and controlling the allocation of network device resources based on the originating entity (in contrast to on a per valid IPv6 address basis), a network service provider can manage its network device resources, such as in a manner to prevent a depletion of resources caused by an originating entity using a plethora valid IPv6 addresses, or a malicious denial-of-service attack.
