<title>The libdhcp++ Library</title>
<para>
libdhcp++ is a library written in C++ that handles
many DHCP-related tasks, including:
<itemizedlist>
<listitem>
<simpara>DHCPv4 and DHCPv6 packets parsing, manipulation and assembly</simpara>
</listitem>
<listitem>
<simpara>Option parsing, manipulation and assembly</simpara>
</listitem>
<listitem>
<simpara>Network interface detection</simpara>
</listitem>
<listitem>
<simpara>Socket operations such as creation, data transmission and reception and socket closing.</simpara>
</listitem>
</itemizedlist>
</para>
<para>
While this library is currently used by Kea, it is designed to
be a portable, universal library, useful for any kind of DHCP-related software.

<title>Interface detection and Socket handling</title>
<para>Both the DHCPv4 and DHCPv6 components share network
interface detection routines. Interface detection is
currently supported on Linux, all BSD family (FreeBSD, NetBSD,
OpenBSD), Mac OS X and Solaris 11 systems.</para>
<para>DHCPv4 requires special raw socket processing to send and receive
packets from hosts that do not have IPv4 address assigned. Support
for this operation is implemented on Linux, FreeBSD, NetBSD and OpenBSD.
It is likely that DHCPv4 component will not work in certain cases on
other systems.</para>
