    • getAddressCount

      @Deprecated public int getAddressCount()
      Deprecated.
      (3.4) use getAddressCountLong() instead
      Gets the count of available addresses. Will be zero for CIDR/31 and CIDR/32 if the inclusive flag is false.
      Returns:
      the count of addresses, may be zero.
      Throws:
      RuntimeException - if the correct count is greater than Integer.MAX_VALUE

    • getAddressCountLong

      public long getAddressCountLong()
      Gets the count of available addresses. Will be zero for CIDR/31 and CIDR/32 if the inclusive flag is false.
      Returns:
      the count of addresses, may be zero.
