Qname minimisation, seen from RIPE Atlas probes
RIPE Atlas probes are typically installed in "geekier" networks so they probably use a QNAME-minimizing resolver more often than ordinary machines.
% blaeu-resolve -r 1000 -q TXT qnamemintest.internet.nl
["no - qname minimisation is not enabled on your resolver :("] : 606 occurrences
["hooray - qname minimisation is enabled on your resolver :)!"] : 375 occurrences
[ (TRUNCATED - May have to use --ednssize) "hooray - qname minimisation is enabled on your resolver :)!"] : 1 occurrences
