I think the answer is in the question. :)

If Option 53 = 0x010d, this means that the message type is DHCPLEASEACTIVE, not
DHCPLEASEQUERY. From RFC 4388:

                        Value   Message Type
                         -----   ------------
                           10    DHCPLEASEQUERY
                           11    DHCPLEASEUNASSIGNED
                           12    DHCPLEASEUNKNOWN
                           13    DHCPLEASEACTIVE

You didn't say what software was issuing the LEASEQUERY, but my guess is that is
the problem.

For the rest of your message:

- - Yes, you need 3.1 because LEASEQUERY support was not added until then.

- - Even if you don't enable LEASEQUERY, you will still see log messages on the
server (which will report that the message is ignored). These are sent to syslog
at a level LOG_INFO.
