<p>Ugg... typo's</p>
<p>Please read that as....</p>
<p>So the correct format to add a "Please delete all DS records for
my domain" is "CDS 0 0 0 00".</p>

<p>Did some more Googling....</p>
<p>So the correct format to add a "Please delete all CD records
for my domain" is "CDC 0 0 0 00".</p>
<p>However, in order to get BIND to accept this, you also have to
have a working DNSKEY (KSK) key in the Zone... that's really
intuitive!<br>
To reduce code changes in my system - I also have a ZSK.<br>
Of course there must be no other CDS keys in the zone - in spite
of one normally doing that when one creates a KSK...<br>

<p>(Thinking about pushing the Start button to stop the machine -
then again, I run Linux)<br>

<p>I'm running Gentoo - and the newest version of BIND in the
repository is bind-9.16.6-r3<br>
Should I not be running what is one version away from the
Current-Stable version?<br>
</p>
<p>The ONLY DNSSEC type record I have in this zone is the "CDS 0
0 0 0" record.</p>
I totally agree with ...<br>
<p>> There must only be the delete cds/cdnskey records and
not any other cds/cdnskey records.<br>
> Publish and delete instructions at the same time is not
consistent.</p>
<p>I'm also not surprised that NET_DNS2 is wrong. Have emailed
the author.</p>
<p>Still - what does one correctly enter into a text based zone?</p>
<p>The text zone currently looks like...<br>

<p>I've seen a record hosted by Cloudflare.... for
revolution.edu.za, DIG shows that as "CDS 0 0 0 00"
