NAME
       dnssec-checkds - DNSSEC delegation consistency checking tool

SYNOPSIS
       dnssec-checkds [-l domain] [-f file] [-d dig path] [-D dsfromkey path]
                      {zone}

       dnssec-dsfromkey [-l domain] [-f file] [-d dig path]
                        [-D dsfromkey path] {zone}

DESCRIPTION
       dnssec-checkds verifies the correctness of Delegation Signer (DS) or
       DNSSEC Lookaside Validation (DLV) resource records for keys in a
       specified zone.

OPTIONS
       -f file
           If a file is specified, then the zone is read from that file to
           find the DNSKEY records. If not, then the DNSKEY records for the
           zone are looked up in the DNS.

       -l domain
           Check for a DLV record in the specified lookaside domain, instead
           of checking for a DS record in the zone's parent. For example, to
           check for DLV records for "example.com" in ISC's DLV zone, use:
           dnssec-checkds -l dlv.isc.org example.com

       -d dig path
           Specifies a path to a dig binary. Used for testing.

       -D dsfromkey path
           Specifies a path to a dnssec-dsfromkey binary. Used for testing.
