55<p><span><strong class="command">dnssec-checkds</strong></span>
56      verifies the correctness of Delegation Signer (DS) or DNSSEC
57      Lookaside Validation (DLV) resource records for keys in a specified
58      zone.

64<dt><span class="term">-f <em class="replaceable"><code>file</code></em></span></dt>
65<dd><p>
66            If a <code class="option">file</code> is specified, then the zone is
67            read from that file to find the DNSKEY records.  If not,
68            then the DNSKEY records for the zone are looked up in the DNS.
69          </p></dd>
70<dt><span class="term">-l <em class="replaceable"><code>domain</code></em></span></dt>
71<dd><p>
72            Check for a DLV record in the specified lookaside domain, 
73            instead of checking for a DS record in the zone's parent.
74            For example, to check for DLV records for "example.com"
75            in ISC's DLV zone, use:
76            <span><strong class="command">dnssec-checkds -l dlv.isc.org example.com</strong></span>
77          </p></dd>

79<dd><p>
80            Specifies a path to a <span><strong class="command">dig</strong></span> binary.  Used
81            for testing.
82          </p></dd>
83<dt><span class="term">-D <em class="replaceable"><code>dsfromkey path</code></em></span></dt>
84<dd><p>
85            Specifies a path to a <span><strong class="command">dnssec-dsfromkey</strong></span> binary.
