Excerpt
Excerpt 7. A method implemented at least in part by a computing device, the method comprising: commanding at least one agent associated with a local link segment to discover at least one network node coupled to the local link segment; and receiving at least one routable site-local address from the agent, wherein the site-local address corresponds to the network node. |

A method comprising:
dynamically scanning a network with a first network scanner;
dynamically scanning the network with a second network scanner;
determining a new network address, wherein the new network address is discovered by the first network scanner and not discovered by the second network scanner; and
updating the second scanner with the new address.

After receiving the Address Harvest command 206 , the agent 114 sends a Neighbor Solicitation message 208 to all nodes 202 on the local link segment 110 . A suitable example of the Neighbor Solicitation message 208 is the message defined under ICMPv6 type 135 , code 0, which may be sent to the link-local multicast address for “all nodes” (ff02::1). (Para 25)
