    • isInRange

      public boolean isInRange(String address)
      Returns true if the parameter address is in the range of usable endpoint addresses for this subnet. This excludes the network and broadcast addresses. Use SubnetUtils.setInclusiveHostCount(boolean) to change this.
      Parameters:
      address - A dot-delimited IPv4 address, e.g. "192.168.0.1"
      Returns:
      True if in range, false otherwise

    • isInRange

      public boolean isInRange(int address)
      Returns true if the parameter address is in the range of usable endpoint addresses for this subnet. This excludes the network and broadcast addresses by default. Use SubnetUtils.setInclusiveHostCount(boolean) to change this.
      Parameters:
      address - the address to check
      Returns:
      true if it is in range
