Generate byte and instance representations of an dns._OPTHeader where all attributes are set to non-default values.

For testing whether attributes have really been read from the byte string during decoding.

Class Method bytes Return bytes representing an encoded OPT record.
Class Method object Return a new dns._OPTHeader instance.
@classmethod
def bytes(cls, excludeName=False, excludeOptions=False): (source)

Return bytes representing an encoded OPT record.

Returns
bytes representing the encoded OPT record returned by object.
@classmethod
def object(cls): (source)

Returns
A dns._OPTHeader instance with attributes that match the encoded record returned by bytes.
