Importing DNS data

NameSurfer 7.6.4.1 |
|||||||||||||||||||||||||||||||||
General
The import form is used to upload DNS data in a text-based file format into NameSurfer. The file to be imported must reside on the machine where you are running your web browser.
Importing a new zone
When the import function is entered through the "Import zone from file" link on the DNS index page, it will attempt to create a new zone from the imported data. The data must be in the DNS master file format (as defined in RFC1035) and must form a complete zone. In particular, it must contain a SOA record.There is a new checkbox for creating/deleting reverse maps automatically, it creates the PTR-records but not the zones so reverse-zones should be created/imported before forward-zones.
There is also a checkbox for 'Keep all TTL values' that is checked on by default. This switch tells import to not modify any of the record TTL values read from the zone file but to import them as-is. To invoke the earlier behavior of updating these values to at least the zone negative caching TTL (original minimum TTL), uncheck this box before upload.
Importing into an existing zone
When the import function is entered through the "Import DNS names" link on the zone page, it will add the imported data to the current zone.Both the UNIX /etc/hosts format and the standard RFC1035 master file format are supported.
Since each resource record in the file will be added to the current zone, all the resource records in the file must belong to it. No data is removed in the import process, so careless use may lead to duplicate records.
This function is intended for amending an existing zone with some new records from a "partial" master file. Note that when importing a DNS master file, the file may not contain a SOA record, because adding a SOA to an existing zone would cause it to have two SOA records - which is an illegal situation.
