Abstract
Methods and apparatus for discovering hosts on an Internet Protocol (IP) version 6 (IPv6) network are disclosed. An example implementation includes probing a network to determine an Internet Protocol (IP) version 4 (IPv4) address that is in use on the network; determining a Media Access Control (MAC) address associated with the IPv4 address; determining a local-prefix; determining a first IP version 6 (IPv6) address, the first IPv6 address including the MAC address and the local-prefix; determining a second IPv6 address, the second IPv6 address including the MAC address and the local-prefix and the second IPv6 address being different than the first IPv6 address; probing the network to determine if the first IPv6 address is in use; probing the network to determine if the second IPv6 address is in use; and storing an indication of whether at least one of the first or second IPv6 address is in use.
