twisted.names.dnsView Source (View In Hierarchy)
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:
|Instance Variable||rname||A domain-name which specifies the mailbox of the person responsible for
this zone. (type:
|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:
|Instance Variable||refresh||A 32 bit time interval before the zone should be refreshed. (type:
|Instance Variable||minimum||The unsigned 32 bit minimum TTL field that should be exported with any RR
from this zone. (type:
|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:
|Instance Variable||retry||A 32 bit time interval that should elapse before a failed refresh should be
|Instance Variable||ttl||The default TTL to use for records served from this zone. (type:
|Method||encode||Write a representation of this object to the given file object.|
|Method||decode||Reconstruct an object from data read from the given file object.|
Inherited from FancyEqMixin:
Inherited from FancyStrMixin:
Write a representation of this object to the given file object.
|Parameters||strio||The stream to which to write bytes (type: File-like object)|
|compDict||A dictionary of backreference addresses that have already been written to
this stream and that may be used for compression. (type: |
Reconstruct an object from data read from the given file object.
|Parameters||strio||The stream 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: |
