<p style="Normal"><c props="font-weight:normal; lang:en-US"></c></p>
<p style="Normal"><c props="font-weight:normal; lang:en-US">DNS is designed to store a number of record types; each type has its own format for storing data.  However, DNS does not have a mechanism for parsing resource record types which are not hard-coded in the DNS server attempting to parse the data in question.</c><c props="font-weight:normal; lang:en-US"></c></p>
<p style="Normal"><c props="font-weight:normal; lang:en-US"></c></p>
<p style="Normal"><c props="font-weight:normal; lang:en-US">The purpose of this document is to start to alleviate this issue.  The most important reason for this is so that new DNS record types can be potentially decompressed without needing to recode legacy DNS servers which do not have knowledge of a new resource record.</c><c props="font-weight:normal; lang:en-US"></c></p>
<p style="Normal"><c props="font-weight:normal; lang:en-US"></c></p>
<p style="Normal"><c props="font-weight:normal; lang:en-US">DNS compression is designed so that, if a DNS server does not know where compressible DNS labels are in the RDDATA for a given record, the server will not be able to decompress the label in question.  Since it is desirable to have new record types be decompressed, there needs to be a way to easily inform DNS servers of the format for resource records.</c><c props="font-weight:normal; lang:en-US"></c></p>
