      The byte value of this opcode.

    • getOpcode

      public static DnsMessage.OPCODE getOpcode(int value) throws IllegalArgumentException
      Retrieve the symbolic name of an opcode byte.
      Parameters:
      value - The byte value of the opcode.
      Returns:
      The symbolic opcode or null.
      Throws:
      IllegalArgumentException - If the byte value is not in the range 0..15.
