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.)
</p>
<p>
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>
<p>
This option is mainly intended for server testing;
there is rarely any benefit in setting a value other
than the default.
