# Additional arguments when starting the pdns daemon
#
#   -mxx  sets the query method pdnsd uses. Possible values for xx are:
#
#         uo - pdnsd will use UDP only. This is the fastest method, and should
#               be supported by all name servers on the Internet.
#
#         to - pdnsd will use TCP only. TCP queries usually take more time than
#               UDP queries, but are more secure against certain attacks, where
#               an attacker tries to guess your query id and to send forged
#               answers. TCP queries are not supported by some name servers.
#
#         tu - pdnsd will try to use TCP, and will fall back to UDP if its
#               connection is refused or times out.
#
#         ut - pdnsd will try to use UDP, and will repeat the query using TCP
#               if the UDP reply was truncated (i.e. the tc bit is set).
#               This is the behaviour recommended by the DNS standards.
#
# the default of "-mtu" causes pdnsd to do tcp first, then udp.
