Class Variable	`showAttributes`	Undocumented
Instance Variable	`address`	The packed network-order representation of the IPv4 address associated with this record.
Instance Variable	`map`	A bitvector indicating the services available at the specified address.
Instance Variable	`protocol`	The 8 bit IP protocol number for which this service map is relevant.
Instance Variable	`ttl`	The maximum number of seconds which this record should be cached.
Property	`_address`	Undocumented

def __init__(self, address='0.0.0.0', protocol=0, map=b'', ttl=None): (source) ¶

Parameters
address:`bytes` or `str`	The IPv4 address associated with this record, in quad-dotted notation.
protocol	Undocumented
map	Undocumented
ttl	Undocumented

def decode(self, strio, length=None): (source) ¶

from twisted.names.dns.IEncodable

Reconstruct an object from data read from the given file object.

Parameters
strio:File-like object	A seekable buffer from which bytes may be read.
length:`int` or `None`	The number of bytes in this RDATA field. Most implementations can ignore this value. Only in the case of records similar to TXT where the total length is in no way encoded in the data is it necessary.

def encode(self, strio, compDict=None): (source) ¶

from twisted.names.dns.IEncodable

Write a representation of this object to the given file object.

Parameters
strio:File-like object	The buffer to write to. It must have a `tell()` method.
compDict:`dict` of `bytes` to `int` r `None`	A mapping of names to byte offsets that have already been written to the buffer, which may be used for compression (see RFC 1035 section 4.1.4). When `None`, encode without compression.
