ancillary agent for inbound zone transfers
[axfr] | [ixfr]
is an ancillary program executed by
to perform an inbound zone transfer. It is rarely executed directly, and then
only by system administrators who are trying to debug a zone transfer problem.
See RFCs 1033, 1034, and 1035 for more information on the Internet
Domain Name System (DNS).
Specifies the name of the zone to be transferred.
Specifies the name of the file,
into which the zone should be dumped
when it is received from the primary server.
Specifies the serial number of our current copy of this zone. If the
we get from the primary server does not have a serial
number higher than this, the transfer will be aborted.

Perform a restricted transfer of only the SOA, NS records and glue A records
for the zone. The SOA record will not be loaded by
but will be used to
determine when to verify the NS records. See the

Additional arguments are taken as name server addresses in
no hostnames are allowed here. At least one address must be specified.
Any additional addresses will be tried, in order, if the first one fails
to transfer to us successfully.
The axfr or ixfr after name server address
designates the type of zone transfer to perform. Use axfr
for a full zone transfer or ixfr for an incremental zone
