<DIV>Dear friends:</DIV>
<DIV>
<DIV class=FoxDiv20141209164319361780 style="BACKGROUND-COLOR: white">
<DIV>When the resolver sends the DNSKEY RR query, irrespecitve
of keyrollover period, I think the response message should reply a
KSK, a ZSK and a RRSIG(DNSKEY). However, when I capture the package with
tcpdump, the response message is unanticipated. </DIV>
<DIV>I get the response with one KSK£¬ two ZSKs and one RRSIG£¨DNSKEY£©while
we send DNSKEY RR query to root.</DIV>
<DIV>For example, </DIV>

<DIV>So, my question is that what is the exact result of DNSKEY RR query, how I
calculate their message size?</DIV></DIV>
