filterBySubnet

public static java.util.Collection<java.net.NetworkInterface> filterBySubnet(java.net.InetAddress address,
                                                                             int subnetPrefix)
                                                                      throws java.net.SocketException

Search for a list of network interfaces that match the specified address and subnet prefix. The results will be ordered by the length of the subnet prefix (InterfaceAddress.getNetworkPrefixLength()). If no results match, then the collection will be empty.

Parameters:

address - to search for on the NetworkInterfaces.

subnetPrefix - to limit the search.

Returns:

NetworkInterfaces that match the supplied criteria, ordered by the length of the subnet prefix. Empty if none match.

Throws:

java.net.SocketException - if an error occurs
