Possible formats are ``text`` (the default), which is the standard
textual representation of the zone, and ``map``, ``raw``, and
``raw=N``, which store the zone in a binary format for rapid
loading by ``named``. ``raw=N`` specifies the format version of the
raw zone file: if ``N`` is 0, the raw file can be read by any version of
``named``; if N is 1, the file can only be read by release 9.9.0 or
higher. The default is 1.
Possible formats are ``"text"`` (default), which is the standard

**-k** mode
Perform ``"check-names"`` checks with the specified failure mode.
Possible modes are ``"fail"`` (default for ``named-compilezone``),
``"warn"`` (default for ``named-checkzone``) and ``"ignore"``.
``-l ttl``
This option sets a maximum permissible TTL for the input file. Any record with a
TTL higher than this value causes the zone to be rejected. This
**-l** ttl
Sets a maximum permissible TTL for the input file. Any record with a
TTL higher than this value will cause the zone to be rejected. This
is similar to using the ``max-zone-ttl`` option in ``named.conf``.
``-L serial``
When compiling a zone to ``raw`` or ``map`` format, this option sets the "source
serial" value in the header to the specified serial number. This is
expected to be used primarily for testing purposes.
**-L** serial
When compiling a zone to "raw" or "map" format, set the "source
serial" value in the header to the specified serial number. (This is
expected to be used primarily for testing purposes.)
``-m mode``
This option specifies whether MX records should be checked to see if they are
addresses. Possible modes are ``fail``, ``warn`` (the default), and
``ignore``.
**-m** mode
Specify whether MX records should be checked to see if they are
addresses. Possible modes are ``"fail"``, ``"warn"`` (default) and

``-M mode``
This option checks whether a MX record refers to a CNAME. Possible modes are
``fail``, ``warn`` (the default), and ``ignore``.
**-M** mode
Check if a MX record refers to a CNAME. Possible modes are
``"fail"``, ``"warn"`` (default) and ``"ignore"``.
``-n mode``
This option specifies whether NS records should be checked to see if they are
addresses. Possible modes are ``fail`` (the default for

and ``"ignore"``.
``-o filename``
This option writes the zone output to ``filename``. If ``filename`` is ``-``, then
the zone output is written to standard output. This is mandatory for ``named-compilezone``.
**-o** filename
Write zone output to ``filename``. If ``filename`` is ``-`` then
write to standard out. This is mandatory for ``named-compilezone``.
``-r mode``
This option checks for records that are treated as different by DNSSEC but are
semantically equal in plain DNS. Possible modes are ``fail``,
``warn`` (the default), and ``ignore``.
**-r** mode
Check for records that are treated as different by DNSSEC but are
semantically equal in plain DNS. Possible modes are ``"fail"``,
``"warn"`` (default) and ``"ignore"``.
``-s style``
This option specifies the style of the dumped zone file. Possible styles are
``full`` (the default) and ``relative``. The ``full`` format is most
suitable for processing automatically by a separate script.
The relative format is more human-readable and is thus
suitable for editing by hand. For ``named-checkzone``, this does not

``dnssec-signzone`` signs a zone; it generates NSEC and RRSIG records
``dnssec-signzone`` signs a zone. It generates NSEC and RRSIG records
and produces a signed version of the zone. The security status of
delegations from the signed zone (that is, whether the child zones are
secure) is determined by the presence or absence of a ``keyset``
secure or not) is determined by the presence or absence of a ``keyset``
file for each child zone.

``-a``
This option verifies all generated signatures.
**-a**
Verify all generated signatures.
``-c class``
This option specifies the DNS class of the zone.

This option indicates the directory where BIND 9 should look for ``dsset-`` or ``keyset-`` files.
**-d** directory
Look for ``dsset-`` or ``keyset-`` files in ``directory``.
``-D``
This option indicates that only those record types automatically managed by

``-E engine``
This option specifies the hardware to use for cryptographic
operations, such as a secure key store used for signing, when applicable.
**-E** engine
When applicable, specifies the hardware to use for cryptographic
operations, such as a secure key store used for signing.
When BIND is built with OpenSSL PKCS#11 support, this defaults to the
string ``pkcs11``, which identifies an OpenSSL engine that can drive a
string "pkcs11", which identifies an OpenSSL engine that can drive a
cryptographic accelerator or hardware service module. When BIND is
built with native PKCS#11 cryptography (``--enable-native-pkcs11``), it
built with native PKCS#11 cryptography (--enable-native-pkcs11), it
defaults to the path of the PKCS#11 provider library specified via

This option indicates that DS records for child zones should be generated from a ``dsset-`` or ``keyset-``
file. Existing DS records are removed.
**-g**

file. Existing DS records will be removed.
``-K directory``
This option specifies the directory to search for DNSSEC keys. If not
specified, it defaults to the current directory.
**-K** directory
Key repository: Specify a directory to search for DNSSEC keys. If not
specified, defaults to the current directory.
``-k key``
This option tells BIND 9 to treat the specified key as a key-signing key, ignoring any key flags. This
**-k** key
Treat specified key as a key signing key ignoring any key flags. This
option may be specified multiple times.
``-M maxttl``
This option sets the maximum TTL for the signed zone. Any TTL higher than ``maxttl``
in the input zone is reduced to ``maxttl`` in the output. This
**-M** maxttl
Sets the maximum TTL for the signed zone. Any TTL higher than maxttl
in the input zone will be reduced to maxttl in the output. This
provides certainty as to the largest possible TTL in the signed zone,
which is useful to know when rolling keys. The maxttl is the longest
which is useful to know when rolling keys because it is the longest
possible time before signatures that have been retrieved by resolvers
expire from resolver caches. Zones that are signed with this
will expire from resolver caches. Zones that are signed with this
option should be configured to use a matching ``max-zone-ttl`` in
``named.conf``. (Note: This option is incompatible with ``-D``,
because it modifies non-DNSSEC data in the output zone.)
``-s start-time``
This option specifies the date and time when the generated RRSIG records become
**-s** start-time
Specify the date and time when the generated RRSIG records become
valid. This can be either an absolute or relative time. An absolute
start time is indicated by a number in YYYYMMDDHHMMSS notation;

``-i interval``
This option indicates that, when a previously signed zone is passed as input, records may be
re-signed. The ``interval`` option specifies the cycle interval as an
offset from the current time, in seconds. If a RRSIG record expires
after the cycle interval, it is retained; otherwise, it is considered
to be expiring soon and it is replaced.

resigned. The ``interval`` option specifies the cycle interval as an
offset from the current time (in seconds). If a RRSIG record expires
after the cycle interval, it is retained. Otherwise, it is considered
to be expiring soon, and it will be replaced.
The default cycle interval is one quarter of the difference between
the signature end and start times. So if neither ``end-time`` nor
``start-time`` is specified, ``dnssec-signzone`` generates
the signature end and start times. So if neither ``end-time`` or
``start-time`` are specified, ``dnssec-signzone`` generates
signatures that are valid for 30 days, with a cycle interval of 7.5
days. Therefore, if any existing RRSIG records are due to expire in
less than 7.5 days, they are replaced.

intended to be used for dynamic signed zones so that the dumped zone
file in a non-text format containing updates can be signed directly.
This option is not useful for non-dynamic zones.
The use of this option does not make much sense for non-dynamic
zones.
``-j jitter``
**-j** jitter
When signing a zone with a fixed signature lifetime, all RRSIG
records issued at the time of signing expire simultaneously. If the
zone is incrementally signed, i.e., a previously signed zone is passed
as input to the signer, all expired signatures must be regenerated
at approximately the same time. The ``jitter`` option specifies a jitter
window that is used to randomize the signature expire time, thus
records issued at the time of signing expires simultaneously. If the
zone is incrementally signed, i.e. a previously-signed zone is passed
as input to the signer, all expired signatures have to be regenerated
at about the same time. The ``jitter`` option specifies a jitter
window that will be used to randomize the signature expire time, thus
spreading incremental signature regeneration over time.
Signature lifetime jitter also, to some extent, benefits validators and
servers by spreading out cache expiration, i.e., if large numbers of
RRSIGs do not expire at the same time from all caches, there is
less congestion than if all validators need to refetch at around the
Signature lifetime jitter also to some extent benefits validators and
servers by spreading out cache expiration, i.e. if large numbers of
RRSIGs don't expire at the same time from all caches there will be
less congestion than if all validators need to refetch at mostly the
same time.

serial" value in the header to the specified ``serial`` number. (This is
**-L** serial
When writing a signed zone to "raw" or "map" format, set the "source

**-n** ncpus
Specifies the number of threads to use. By default, one thread is
started for each detected CPU.
``-N soa-serial-format``
This option sets the SOA serial number format of the signed zone. Possible formats are
``keep`` (the default), ``increment``, ``unixtime``, and
``date``.
**-N** soa-serial-format
The SOA serial number format of the signed zone. Possible formats are
``"keep"`` (default), ``"increment"``, ``"unixtime"``, and
``"date"``.
**keep**
This format indicates that the SOA serial number should not be modified.
``"keep"``
Do not modify the SOA serial number.
**increment**
This format increments the SOA serial number using :rfc:`1982` arithmetic.
``"increment"``
Increment the SOA serial number using :rfc:`1982` arithmetic.
**unixtime**
This format sets the SOA serial number to the number of seconds since the beginning of the Unix epoch.
``"unixtime"``
Set the SOA serial number to the number of seconds since epoch.
**date**
This format sets the SOA serial number to today's date, in YYYYMMDDNN format.

algorithm found in the DNSKEY RRset for the zone, and that the NSEC /
NSEC3 chains are complete.
Options
~~~~~~~
``-c class``
This option specifies the DNS class of the zone.
**-c** class
Specifies the DNS class of the zone.
``-E engine``
This option specifies the cryptographic hardware to use, when applicable.
**-E** engine
Specifies the cryptographic hardware to use, when applicable.
When BIND is built with OpenSSL PKCS#11 support, this defaults to the
string ``pkcs11``, which identifies an OpenSSL engine that can drive a
string "pkcs11", which identifies an OpenSSL engine that can drive a
cryptographic accelerator or hardware service module. When BIND is
built with native PKCS#11 cryptography (``--enable-native-pkcs11``), it
built with native PKCS#11 cryptography (--enable-native-pkcs11), it
defaults to the path of the PKCS#11 provider library specified via
``--with-pkcs11``.
"--with-pkcs11".
``-I input-format``
This option sets the format of the input zone file. Possible formats are ``text``
(the default) and ``raw``. This option is primarily intended to be used
for dynamic signed zones, so that the dumped zone file in a non-text
format containing updates can be verified independently.
This option is not useful for non-dynamic zones.
**-I** input-format
The format of the input zone file. Possible formats are ``"text"``
(default) and ``"raw"``. This option is primarily intended to be used
for dynamic signed zones so that the dumped zone file in a non-text
format containing updates can be verified independently. The use of
this option does not make much sense for non-dynamic zones.
``-o origin``
This option indicates the zone origin. If not specified, the name of the zone file is
**-o** origin
The zone origin. If not specified, the name of the zone file is
assumed to be the origin.
``-v level``
This option sets the debugging level.
**-v** level
Sets the debugging level.
``-V``
This option prints version information.
**-V**
Prints version information.
``-q``
This option sets quiet mode, which suppresses output. Without this option, when ``dnssec-verify``
is run it prints to standard output the number of keys in use, the
algorithms used to verify the zone was signed correctly, and other status
information. With this option, all non-error output is suppressed, and only the exit
code indicates success.
Quiet mode: Suppresses output. Without this option, when ``dnssec-verify``
is run it will print to standard output the number of keys in use, the
algorithms used to verify the zone was signed correctly and other status
information. With it, all non-error output is suppressed, and only the exit
code will indicate success.
``-x``
This option verifies only that the DNSKEY RRset is signed with key-signing keys.
Without this flag, it is assumed that the DNSKEY RRset is signed
by all active keys. When this flag is set, it is not an error if
**-x**
Only verify that the DNSKEY RRset is signed with key-signing keys.
Without this flag, it is assumed that the DNSKEY RRset will be signed
by all active keys. When this flag is set, it will not be an error if
the DNSKEY RRset is not signed by zone-signing keys. This corresponds
to the ``-x`` option in ``dnssec-signzone``.
``-z``
This option indicates that the KSK flag on the keys should be ignored when determining whether the zone is
correctly signed. Without this flag, it is assumed that there is
**-z**
Ignore the KSK flag on the keys when determining whether the zone if
correctly signed. Without this flag it is assumed that there will be
a non-revoked, self-signed DNSKEY with the KSK flag set for each
algorithm, and that RRsets other than DNSKEY RRset are signed with
algorithm and that RRsets other than DNSKEY RRset will be signed with
a different DNSKEY without the KSK flag set.
With this flag set, BIND 9 only requires that for each algorithm, there
be at least one non-revoked, self-signed DNSKEY, regardless of
the KSK flag state, and that other RRsets be signed by a
With this flag set, we only require that for each algorithm, there
will be at least one non-revoked, self-signed DNSKEY, regardless of
the KSK flag state, and that other RRsets will be signed by a
non-revoked key for the same algorithm that includes the self-signed
key; the same key may be used for both purposes. This corresponds to
the ``-z`` option in ``dnssec-signzone``.
``zonefile``
This option indicates the file containing the zone to be signed.
**zonefile**
The file containing the zone to be signed.

The command formats and their meaning are as follows:
``server servername port``
This command sends all dynamic update requests to the name server ``servername``.
When no server statement is provided, ``nsupdate`` sends updates
to the primary server of the correct zone. The MNAME field of that
zone's SOA record identify the primary server for that zone.
``server`` servername port
Sends all dynamic update requests to the name server ``servername``.
When no server statement is provided, ``nsupdate`` will send updates
to the master server of the correct zone. The MNAME field of that
zone's SOA record will identify the master server for that zone.
``port`` is the port number on ``servername`` where the dynamic
update requests are sent. If no port number is specified, the default
update requests get sent. If no port number is specified, the default
DNS port number of 53 is used.
``local address port``
This command sends all dynamic update requests using the local ``address``. When
no local statement is provided, ``nsupdate`` sends updates using
an address and port chosen by the system. ``port`` can also
be used to force requests to come from a specific port. If no port number
is specified, the system assigns one.
``local`` address port
Sends all dynamic update requests using the local ``address``. When
no local statement is provided, ``nsupdate`` will send updates using
an address and port chosen by the system. ``port`` can additionally
be used to make requests come from a specific port. If no port number
is specified, the system will assign one.

``none`` clears the default TTL.
``ttl`` seconds
Specify the default time to live for records to be added. The value
``none`` will clear the default ttl.
``key hmac:keyname secret``
This command specifies that all updates are to be TSIG-signed using the
``keyname``-``secret`` pair. If ``hmac`` is specified, it sets
the signing algorithm in use. The default is ``hmac-md5``; if MD5
was disabled, the default is ``hmac-sha256``. The ``key`` command overrides any key
