Hi All,
<div><br>
</div>
<div>Is there a limit to the number of SRV records that NSD will
return, outside of the upper bound on packet size? I have a name
that has ~18 SRV records, and I only see the same four, always.
The packet size out on the wire is 260B, so I would expect we
could cram some more in there, and I am not sure why we are only
ever seeing the same five. </div>

<div>I wanted to ask before burning time on a source-code
code-dive. I am using nsd 3.2.5.</div>

Remember NSD doesn't rotate records in the same set (or in any
case). Also, you aren't going through a caching server are you?<br>

That was just me quickly creating some entries on a test zone.
Often caching servers limit the number of RR's to whatever they feel
like (4 seems common). That's just my experience.<span class="HOEnZb"><font color="#888888"><br>
