1. A computer-implemented method of persistently identifying nodes in networks having transient network communities where a collection of nodes making up a network is dynamically changeable over time, comprising steps of:

  • assigning an initial network address to each node upon its initial entry into the network;

    creating, for each of the nodes upon the initial entry of the node into the network, a persistent node identifier to uniquely identify the node across all of that node'"'"'s entries into the network, wherein the persistent node identifier for each of the nodes comprises;

    (1) a network domain identifier of a network domain in which the initial entry occurred;

    (2) the initial network address of the node; and

    (3) a timestamp representing when the initial network entry occurred;

    storing a mapping between the initial network address and the persistent node identifier for each of the nodes; and

    using the persistent node identifier to resolve each node'"'"'s identity upon its subsequent entry into the network, even if a different network address is assigned to the node upon the subsequent entry.
