faa1795a28a5c712eed6d0a3f84d98c368a316c6jb core of the new system was described in 1983 in RFCs 882 and
faa1795a28a5c712eed6d0a3f84d98c368a316c6jb 883. From 1984 to 1987, the ARPAnet (the precursor to today's
faa1795a28a5c712eed6d0a3f84d98c368a316c6jb Internet) became a testbed of experimentation for developing the
faa1795a28a5c712eed6d0a3f84d98c368a316c6jb new naming/addressing scheme in a rapidly expanding,
faa1795a28a5c712eed6d0a3f84d98c368a316c6jb operational network environment. New RFCs were written and
faa1795a28a5c712eed6d0a3f84d98c368a316c6jb published in 1987 that modified the original documents to
faa1795a28a5c712eed6d0a3f84d98c368a316c6jb incorporate improvements based on the working model. RFC 1034,
faa1795a28a5c712eed6d0a3f84d98c368a316c6jb "Domain Names-Concepts and Facilities", and RFC 1035, "Domain
faa1795a28a5c712eed6d0a3f84d98c368a316c6jb Names-Implementation and Specification" were published and
faa1795a28a5c712eed6d0a3f84d98c368a316c6jb became the standards upon which all <acronym class="acronym">DNS</acronym> implementations are
faa1795a28a5c712eed6d0a3f84d98c368a316c6jb built.

faa1795a28a5c712eed6d0a3f84d98c368a316c6jb IPv6 addresses are 128-bit identifiers for interfaces and
faa1795a28a5c712eed6d0a3f84d98c368a316c6jb sets of interfaces which were introduced in the <acronym class="acronym">DNS</acronym> to facilitate
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw scalable Internet routing. There are three types of addresses: <span class="emphasis"><em>Unicast</em></span>,
faa1795a28a5c712eed6d0a3f84d98c368a316c6jb an identifier for a single interface;

faa1795a28a5c712eed6d0a3f84d98c368a316c6jb an identifier for a set of interfaces; and <span class="emphasis"><em>Multicast</em></span>,
faa1795a28a5c712eed6d0a3f84d98c368a316c6jb an identifier for a set of interfaces. Here we describe the global

da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw The Interface Identifier must be unique on the local link,
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw and is usually generated automatically by the IPv6
2c2961f8403049d948b9f3e6c35d6488b6b7e1aajose borrego implementation, although it is usually possible to
7b59d02d2a384be9a08087b14defadd214b3c1ddjb override the default setting if necessary. A typical IPv6
2c2961f8403049d948b9f3e6c35d6488b6b7e1aajose borrego address might look like:
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw <span><strong class="command">2001:db8:201:9:a00:20ff:fe81:2b32</strong></span>

da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw IPv6 address specifications often contain long strings
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw of zeros, so the architects have included a shorthand for
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw specifying
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw them. The double colon (`::') indicates the longest possible
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw string
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw of zeros that can fit, and can be used only once in an address.

<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>

<a name="id2609965"></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>

<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>

<a name="id2609152"></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 name="id2609187"></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>
<p>
Options and Arguments:
</p>
<div class="variablelist"><dl>
<dt><span class="term">
-t RRtype
</span></dt>
<dd><p>
specify the RR type of the query. The default is the A RR.
</p></dd>
<dt><span class="term">
[-a algorithm] [-e] -k keyname -K keystring
</span></dt>
<dd>
<p>
specify a command-line DNS key to validate the answer. For
example, to specify the following DNSKEY of example.com:
</p>
<div class="literallayout"><p><br>
����������������example.com.�3600�IN�DNSKEY�257�3�5�xxx<br>

specify the options as follows:
</p>
<pre class="screen">
<strong class="userinput"><code>
-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

<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>.

<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.

<a name="id2609478"></a>sample-update: a simple dynamic update client program</h4></div></div></div>
<p>
It accepts a single update command as a

authoritative server, and shows the response from the server. In
other words, this is a simplified <span><strong class="command">nsupdate</strong></span>.

specify an IP address of a recursive (caching) name server.
nsprobe uses this server to get the NS RRset of each domain and
the A and/or AAAA RRsets for the name servers. The default
value is 127.0.0.1.
</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.
