>From my own limited investigations (less than 10 servers, but millions of DNS queries thus hopefully somewhat statistically significant): Authoritative servers: 35 - 45% Recursive servers: In the noise (less than 0.5%) which seems to indicate that there are quite a few recursive servers out there that set the DO bit when querying authoritative servers. One of the authoritative servers measured is a ccTLD server for .no.
