setLookupAddresses sets the lookup target address [ipv4]
 
    An address can be any unicast or broadcast ipv4 address.
    In most cases, it is best to let the system determine the
    correct addresses using '*'. However, if the network does
    not support broadcasting, or is otherwise restricted, it
    can be necessary to set addresses manually.
 
    The default behavior can be changed in the config script.
 
    Example
       % Custom addressing
       addresses = {
           '10.10.10.255'
           '192.168.0.255'
       };
       HebiLookup.setLookupAddresses(addresses);
