Dear Team,

 

We have a Authenticated Response in DNSSEC through trust chain.

Now my question is why we itself need a NSEC when we get response from
DNSSEC enabled server authentically.

 

Means, if a Record exist in DNSSEC, then it replies the answer along with
RRSIG of that RR. 

AND if domain doesn't exist, then it can simply give NXDOMAIN and our job
will be done as we trust that nameserver through trust chain.

So what's the need of NSEC??????

 

Thanks n Regards,
