</div></div>Well Apple registered a SRV record for UPDATE so that UPDATEs don't<br>
need to go to the NS's. In theory if the update client supports<br>
the SRV record (there is a ticket to add this feature to nsupdate)<br>
then there is a way to signal this.<br>
<br>
dns-update is the registered string.<br>

If absence of the relevant SRV record indicates fallback to MNAME then it doesn't solve the problem.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><br>
