14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt This is particularly useful with <code class="option">inline-signing</code>
14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt zones that have been reset. Setting the serial number to a value
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein larger than that on the slaves will trigger an AXFR-style
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein transfer.

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein When answering recursive queries, SERVFAIL responses can now be
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein cached by the server for a limited time; subsequent queries for
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein the same query name and type will return another SERVFAIL until
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein the cache times out. This reduces the frequency of retries
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein when a query is persistently failing, which can be a burden
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein on recursive serviers. The SERVFAIL cache timeout is controlled
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein by <code class="option">servfail-ttl</code>, which defaults to 10 seconds
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein and has an upper limit of 30.

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein The new <span><strong class="command">rndc nta</strong></span> command can now be used to
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein set a "negative trust anchor" (NTA), disabling DNSSEC validation for
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein a specific domain; this can be used when responses from a domain
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein are known to be failing validation due to administrative error
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein rather than because of a spoofing attack. NTAs are strictly

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Although the "official" beginning of the Domain Name
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein System occurred in 1984 with the publication of RFC 920, the
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein core of the new system was described in 1983 in RFCs 882 and
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein 883. From 1984 to 1987, the ARPAnet (the precursor to today's
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Internet) became a testbed of experimentation for developing the
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein new naming/addressing scheme in a rapidly expanding,
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User operational network environment. New RFCs were written and
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User published in 1987 that modified the original documents to
71c66a876ecca77923638d3f94cc0783152b2f03Mark Andrews incorporate improvements based on the working model. RFC 1034,
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein "Domain Names-Concepts and Facilities", and RFC 1035, "Domain
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Names-Implementation and Specification" were published and
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein became the standards upon which all <acronym class="acronym">DNS</acronym> implementations are
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein built.

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein IPv6 addresses are 128-bit identifiers for interfaces and
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein sets of interfaces which were introduced in the <acronym class="acronym">DNS</acronym> to facilitate
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein scalable Internet routing. There are three types of addresses: <span class="emphasis"><em>Unicast</em></span>,
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein an identifier for a single interface;
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein <span class="emphasis"><em>Anycast</em></span>,
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User an identifier for a set of interfaces; and <span class="emphasis"><em>Multicast</em></span>,
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User an identifier for a set of interfaces. Here we describe the global
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein Unicast address scheme. For more information, see RFC 3587,
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein "Global Unicast Address Format."

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein IPv6 unicast addresses consist of a
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein <span class="emphasis"><em>global routing prefix</em></span>, a
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein <span class="emphasis"><em>subnet identifier</em></span>, and an
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User <span class="emphasis"><em>interface identifier</em></span>.

7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User The global routing prefix is provided by the
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User upstream provider or ISP, and (roughly) corresponds to the
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein IPv4 <span class="emphasis"><em>network</em></span> section
af40ebed6257e4ac1996144530b3de317cf4da11Tinderbox User of the address range.
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User The subnet identifier is for local subnetting, much the
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User same as subnetting an
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User IPv4 /16 network into /24 subnets.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein The interface identifier is the address of an individual
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein interface on a given network; in IPv6, addresses belong to
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein interfaces rather than to machines.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein </p>
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein<p>
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein The subnetting capability of IPv6 is much more flexible than
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein that of IPv4: subnetting can be carried out on bit boundaries,
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein in much the same way as Classless InterDomain Routing
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein (CIDR), and the DNS PTR representation ("nibble" format)
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein makes setting up reverse zones easier.

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein The Interface Identifier must be unique on the local link,
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein and is usually generated automatically by the IPv6
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein implementation, although it is usually possible to
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein override the default setting if necessary. A typical IPv6
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein address might look like:
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein <span><strong class="command">2001:db8:201:9:a00:20ff:fe81:2b32</strong></span>

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein IPv6 address specifications often contain long strings
b05bdb520d83f7ecaad708fe305268c3420be01dMark Andrews of zeros, so the architects have included a shorthand for
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein specifying
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein them. The double colon (`::') indicates the longest possible
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User string
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User of zeros that can fit, and can be used only once in an address.

Internet Drafts (IDs) are rough-draft working documents of
the Internet Engineering Task Force. They are, in essence, RFCs
in the preliminary stages of development. Implementors are
cautioned not
to regard IDs as archival, and they should not be quoted or cited
in any formal documents unless accompanied by the disclaimer that
they are "works in progress." IDs have a lifespan of six months
after which they are deleted unless updated by their authors.

<a name="bind9.library"></a>BIND 9 DNS Library Support</h2></div></div></div>
<p>This version of BIND 9 "exports" its internal libraries so
that they can be used by third-party applications more easily (we
call them "export" libraries in this document). In addition to
all major DNS-related APIs BIND 9 is currently using, the export
libraries provide the following features:</p>
<div class="itemizedlist"><ul type="disc">
<li><p>The newly created "DNS client" module. This is a higher
level API that provides an interface to name resolution,
single DNS transaction with a particular server, and dynamic
update. Regarding name resolution, it supports advanced
features such as DNSSEC validation and caching. This module
supports both synchronous and asynchronous mode.</p></li>
<li><p>The new "IRS" (Information Retrieval System) library.
It provides an interface to parse the traditional resolv.conf
file and more advanced, DNS-specific configuration file for
the rest of this package (see the description for the
dns.conf file below).</p></li>
<li><p>As part of the IRS library, newly implemented standard
address-name mapping functions, getaddrinfo() and
getnameinfo(), are provided. They use the DNSSEC-aware
validating resolver backend, and could use other advanced
features of the BIND 9 libraries such as caching. The
getaddrinfo() function resolves both A and AAAA RRs
concurrently (when the address family is unspecified).</p></li>
<li><p>An experimental framework to support other event
libraries than BIND 9's internal event task system.</p></li>
</ul></div>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="id2614510"></a>Prerequisite</h3></div></div></div>
<p>GNU make is required to build the export libraries (other
part of BIND 9 can still be built with other types of make). In
the reminder of this document, "make" means GNU make. Note that
in some platforms you may need to invoke a different command name
than "make" (e.g. "gmake") to indicate it's GNU make.</p>
</div>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">

<pre class="screen">
$ <strong class="userinput"><code>/configure --enable-exportlib <em class="replaceable"><code>[other flags]</code></em></code></strong>
$ <strong class="userinput"><code>make</code></strong>
</pre>
<p>
This will create (in addition to usual BIND 9 programs) and a
separate set of libraries under the lib/export directory. For
example, <code class="filename">lib/export/dns/libdns.a</code> is the archive file of the
export version of the BIND 9 DNS library. Sample application
programs using the libraries will also be built under the
lib/export/samples directory (see below).</p>
</div>

<div class="titlepage"><div><div><h3 class="title">
<a name="id2611541"></a>Installation</h3></div></div></div>
<pre class="screen">
$ <strong class="userinput"><code>cd lib/export</code></strong>
$ <strong class="userinput"><code>make install</code></strong>
</pre>
<p>
This will install library object files under the directory
specified by the --with-export-libdir configure option (default:
EPREFIX/lib/bind9), and header files under the directory
specified by the --with-export-includedir configure option
(default: PREFIX/include/bind9).
Root privilege is normally required.
"<span><strong class="command">make install</strong></span>" at the top directory will do the
same.

application after the installation, see

<a name="id2611572"></a>Known Defects/Restrictions</h3></div></div></div>
<div class="itemizedlist"><ul type="disc">
<li><p>Currently, win32 is not supported for the export
library. (Normal BIND 9 application can be built as
before).</p></li>
<li>
<p>The "fixed" RRset order is not (currently) supported in
the export library. If you want to use "fixed" RRset order
for, e.g. <span><strong class="command">named</strong></span> while still building the
export library even without the fixed order support, build
them separately:
</p>
<pre class="screen">

$ <strong class="userinput"><code>make</code></strong>
</pre>
<p>
</p>
</li>
<li><p>The client module and the IRS library currently do not
support DNSSEC validation using DLV (the underlying modules
can handle it, but there is no tunable interface to enable
the feature).</p></li>
<li><p>RFC 5011 is not supported in the validating stub
resolver of the export library. In fact, it is not clear
whether it should: trust anchors would be a system-wide
configuration which would be managed by an administrator,
while the stub resolver will be used by ordinary applications
run by a normal user.</p></li>
<li><p>Not all common <code class="filename">/etc/resolv.conf</code>
options are supported
in the IRS library. The only available options in this
version are "debug" and "ndots".</p></li>

<a name="id2613833"></a>The dns.conf File</h3></div></div></div>
<p>The IRS library supports an "advanced" configuration file
related to the DNS library for configuration parameters that
would be beyond the capability of the
<code class="filename">resolv.conf</code> file.
Specifically, it is intended to provide DNSSEC related
configuration parameters. By default the path to this
configuration file is <code class="filename">/etc/dns.conf</code>.
This module is very
experimental and the configuration syntax or library interfaces
may change in future versions. Currently, only the
<span><strong class="command">trusted-keys</strong></span>
statement is supported, whose syntax is the same as the same name
of statement for <code class="filename">named.conf</code>. (See
<a href="Bv9ARM.ch06.html#trusted-keys" title="trusted-keys Statement Grammar">the section called &#8220;<span><strong class="command">trusted-keys</strong></span> Statement Grammar&#8221;</a> for details.)</p>

<a name="id2613868"></a>sample: a simple stub resolver utility</h4></div></div></div>
<p>
It sends a query of a given name (of a given optional RR type) to a
specified recursive server, and prints the result as a list of
RRs. It can also act as a validating stub resolver if a trust
anchor is given via a set of command line options.</p>
<p>
Usage: sample [options] server_address hostname

<p>
Options and Arguments:
</p>
<div class="variablelist"><dl>

-e -k example.com -K "xxx"
</code></strong>
</pre>
<p>
-e means that this key is a zone's "key signing key" (as known
as "secure Entry point").
When -a is omitted rsasha1 will be used by default.
</p>
</dd>
<dt><span class="term">
-s domain:alt_server_address
</span></dt>
<dd><p>
specify a separate recursive server address for the specific
"domain". Example: -s example.com:2001:db8::1234
</p></dd>

<div class="titlepage"><div><div><h4 class="title">
<a name="id2614027"></a>sample-async: a simple stub resolver, working asynchronously</h4></div></div></div>
<p>
Similar to "sample", but accepts a list

asynchronously.</p>
<p>
Usage: sample-async [-s server_address] [-t RR_type] input_file</p>
<p>
Options and Arguments:
</p>
<div class="variablelist"><dl>
<dt><span class="term">

specify the RR type of the queries. The default is the A
RR.
</dd>
<dt><span class="term">

<a name="id2614285"></a>sample-request: a simple DNS transaction client</h4></div></div></div>
<p>
It sends a query to a specified server, and
prints the response with minimal processing. It doesn't act as a
"stub resolver": it stops the processing once it gets any
response from the server, whether it's a referral or an alias
(CNAME or DNAME) that would require further queries to get the
ultimate answer. In other words, this utility acts as a very
simplified <span><strong class="command">dig</strong></span>.

<a name="id2614418"></a>sample-gai: getaddrinfo() and getnameinfo() test code</h4></div></div></div>
<p>
This is a test program
to check getaddrinfo() and getnameinfo() behavior. It takes a
host name as an argument, calls getaddrinfo() with the given host
name, and calls getnameinfo() with the resulting IP addresses
returned by getaddrinfo(). If the dns.conf file exists and
defines a trust anchor, the underlying resolver will act as a
validating resolver, and getaddrinfo()/getnameinfo() will fail
with an EAI_INSECUREDATA error when DNSSEC validation fails.

<div class="titlepage"><div><div><h4 class="title">
<a name="id2614433"></a>sample-update: a simple dynamic update client program</h4></div></div></div>
<p>
It accepts a single update command as a
command-line argument, sends an update request message to the
authoritative server, and shows the response from the server. In
other words, this is a simplified <span><strong class="command">nsupdate</strong></span>.

<dd><p>
An IP address of the authoritative server that has authority
for the zone containing the update name. This should normally
be the primary authoritative server that accepts dynamic
updates. It can also be a secondary server that is configured
to forward update requests to the primary server.
</p></dd>
<dt><span class="term">
-k keyfile
</span></dt>
<dd><p>
A TSIG key file to secure the update transaction. The keyfile
format is the same as that for the nsupdate utility.
</p></dd>
<dt><span class="term">
-p prerequisite
</span></dt>
<dd><p>
A prerequisite for the update (only one prerequisite can be
specified). The prerequisite format is the same as that is
accepted by the nsupdate utility.

<dd><p>
An IP address of a recursive server that this utility will
use. A recursive server may be necessary to identify the

</p></dd>
<dt><span class="term">
input_file
</span></dt>
<dd><p>
a file name containing a list of domain (zone) names to be

line of the input file specifies a single domain name such as
"example.com". In general this domain name must be the apex
name of some DNS zone (unlike normal "host names" such as
"www.example.com"). nsprobe first identifies the NS RRsets for
the given domain name, and sends A and AAAA queries to these
servers for some "widely used" names under the zone;
specifically, adding "www" and "ftp" to the zone name.
