<listitem>
<para><emphasis role="bold">IPMARK</emphasis> ‒ Assigns a mark
to each matching packet based on the either the source or
destination IP address. By default, it assigns a mark value
equal to the low-order 8 bits of the source address. Default
values are:</para>
<simplelist>
<member>src</member>
<member><emphasis>mask1</emphasis> = 0xFF</member>
<member><emphasis>mask2</emphasis> = 0x00</member>
<member><emphasis>shift</emphasis> = 0</member>
</simplelist>
<para>'src' and 'dst' specify whether the mark is to be based on
the source or destination address respectively. The selected
address is first LANDed with <emphasis>mask1</emphasis> then
LORed with <emphasis>ma<emphasis>s</emphasis>k2</emphasis>. The
result is then shifted <emphasis>shift</emphasis> bits to the
right.</para>
<para>Example:</para>
<blockquote>
<para><simplelist>
<member>IPMARK(dst, 0XFF00, 0x8000,8)</member>
<member>Destination IP address is 192.168.4.3 =
0xc0a80103</member>
</simplelist>Meaning:</para>
<simplelist>
<member>0xc0a80403 LAND 0xFF00 = 0x0400</member>
<member>0x0400 LOR 0x80 = 0x8400</member>
<member>0x8400 &gt;&gt; 8 = 0x84</member>
<member>Mark = 0x84 = 132</member>
