them out manually. $GENERATE just helps condense the zone file, but has no impact on overall operation.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif"">Dear all,<br>
<br>
Is there a difference between the configuration of a set of A records using:<br>
<br>
<br>
1) GENERATE command like: $GENERATE 0-255 $-1.2.3 A 3.2.1.$ <br>
<br>
<br>
2) Defining all the records one by one.<br>
<br>
<br>
<br>
<br>
- difference in the amount of memory used?<br>
<br>
- difference in the speed to retrive the answer.<br>
<br>
<br>
If GENERATE command is used ==> is the answer "calculated" at the query incoming or are all the records already present in memory?<br>
<br>
<br>
Thanks in advance for your feedback,<br>
