+                  This is an upper bound on the uncompressed size of DNS
+                  messages used in zone transfers over TCP.  If a message
+                  grows larger than this size, additional messages will be
+                  used to complete the zone transfer.  (Note, however,
+                  that this is a hint, not a hard limit; if a message
+                  contains a single resource record whose RDATA does not
+                  fit within the size limit, a larger message will be
+                  permitted so the record can be transferred.)

+                  Valid values are between 512 and 65535 octets, and any
+                  values outside that range will be adjusted to the nearest
+                  value within it.  The default is <code class="literal">20480</code>,
+                  which was selected to improve message compression:
+                  most DNS messages of this size will compress to less
+                  than 16536 bytes.  Larger messages cannot be compressed
+                  as effectively, because 16536 is the largest permissible
+                  compression offset pointer in a DNS message.

+<p>
+                  This option is mainly intended for server testing;
+                  there is rarely any benefit in setting a value other
