Like this:

[1218876864] unbound[9689:0] notice: wrong 0x20-ID in reply qname, answer dropped
[1218876864] unbound[9689:0] info: from server 62.212.64.121 port 53
[1218876864] unbound[9689:0] info: for packet[79:0] B32C840000010001000000000236350332303102313702383507696E2D61646472046172706100000C0001C00C000C000100015180001809686F737465642D6279086C6561736577656203636F6D00

The above 0x20 failure is because the leaseweb.nl name servers,

ns1.leaseweb.nl.        A       62.212.64.121
ns4.leaseweb.net.       A       62.212.78.199
ns5.leaseweb.nl.        A       83.149.64.123

downcase everything, presumably because they are behind some sort of
load balancer.
