Abstract
Techniques are described for recording stateless internet protocol (IP) addresses. A DHCP server may receive information requests and/or other communications from a stateless IPv6 client that can be employed to ascertain corresponding IP addresses generated by the client. In one approach, the DHCP server is configured to parse appropriate communications to find information indicative of a stateless IP address. This may include extracting a subnet prefix of the IPv6 client and an interface ID which identifies the specific network interface employed by the client for communications. The DHCP server uses this information to generate corresponding IP addresses. The DHCP server records the extracted information and/or generated addresses in its database (e.g., IP address event log). The DHCP server is then able to provide a count of clients and percentage utilization for a network using the recorded addressing information.
