<br>
<tt><font face="Courier New">
The process for obtaining and authenticating this
initial</font></tt><br>
<tt><font face="Courier New"> trust anchor is achieved via some external
mechanism. For example, a</font></tt><br>
<tt><font face="Courier New"> resolver could use some off-line

</font></tt><br>

<br>
<tt><font face="Courier New">
For an authoritative only setup I would be using TSIG to validate</font></tt><br>

the zone transfers as you have a existing trust relationship.</font></tt><br>

If you want other people to be able to validate the data</font></tt><br>
