+	<blockquote cite="https://kb.isc.org/article/AA-01390">
+	  <p>DNS protocols were designed with the assumption that a certain
+	    amount of trust could be presumed between the operators of primary
+	    and secondary servers for a given zone. However, in current
+	    practice some organizations have scenarios which require them to
+	    accept zone data from sources that are not fully trusted (for
+	    example: providers of secondary name service). A party who is
+	    allowed to feed data into a zone (e.g. by AXFR, IXFR, or Dynamic DNS
+	    updates) can overwhelm the server which is accepting data by
+	    intentionally or accidentally exhausting that server's memory.</p>
