      public class IPAddressMap<TYPE>
      extends HashMap<String,TYPE>

  Internet address map to object

  Internet addresses may be specified as absolute address or as a combination of four octet wildcard specifications (a.b.c.d) that are defined as follows.

       nnn - an absolute value (0-255)
       mmm-nnn - an inclusive range of absolute values,
                 with following shorthand notations:
                 nnn- => nnn-255
                 -nnn => 0-nnn
                 -    => 0-255
       a,b,... - a list of wildcard specifications
