axfr - Perform a DNS zone transfer
axfr [ -fqs ] [ -D directory ] [ @nameserver ] zone
axfr performs a DNS zone transfer, prints each record to the standard output, and stores the zone to a file. If the zone has already been stored in a file, axfr will read the file instead of performing a zone transfer.
Zones will be stored in a directory hierarchy. For example, the zone transfer for foo.bar.com will be stored in the file $HOME/.dns-zones/com/bar/foo/axfr. The directory can be changed with the -D option.
This programs requires that the Storable module be installed.
Force a zone transfer, even if the zone has already been stored in a file.
Be quiet -- don't print the records from the zone.
Perform a zone transfer if the SOA serial number on the nameserver is different than the serial number in the zone file.
Store zone files under directory instead of the default directory (see "FILES").
Query nameserver instead of the default nameserver.
Default directory for storing zone files.
