class documentationtwisted.names.dns
(View In Hierarchy)
Implements interfaces: twisted.names.dns.IEncodable, twisted.names.dns.IRecord
Marks the start of a zone of authority.
This record describes parameters which are shared by all records within a particular zone.
Instance Variable | mname | The domain-name of the name server that was the original or primary source
of data for this zone. (type: Name ) |
Instance Variable | rname | A domain-name which specifies the mailbox of the person responsible for
this zone. (type: Name ) |
Instance Variable | serial | The unsigned 32 bit version number of the original copy of the zone. Zone
transfers preserve this value. This value wraps and should be compared
using sequence space arithmetic. (type: int ) |
Instance Variable | refresh | A 32 bit time interval before the zone should be refreshed. (type: int ) |
Instance Variable | minimum | The unsigned 32 bit minimum TTL field that should be exported with any RR
from this zone. (type: int ) |
Instance Variable | expire | A 32 bit time value that specifies the upper limit on the time interval
that can elapse before the zone is no longer authoritative. (type: int ) |
Instance Variable | retry | A 32 bit time interval that should elapse before a failed refresh should be
retried. (type: int ) |
Instance Variable | ttl | The default TTL to use for records served from this zone. (type: int ) |

Parameters | mname | See Record_SOA.mname (type: bytes
or unicode ) |
rname | See Record_SOA.rname (type: bytes
or unicode ) |
Write a representation of this object to the given file object.
Parameters | strio | The buffer to write to. It must have a tell() method. (type: File-like object) |
compDict | 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. (type: dict
of bytes
to int
r None ) |
Reconstruct an object from data read from the given file object.
Parameters | strio | A seekable buffer from which bytes may be read. (type: File-like object) |
length | 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. (type: int
or None ) |
