Some basic stats:

27 million resolvers existed as of this dataset collection

only 2.1 million of them were "closed".

We have a lot to do to close the hosts, please do what you can to help.

What's the current BCP on how to deal with mobile devices that hard-code
your resolvers in their equivalent of /etc/resolv.conf (often because the
owner of the device trusts their emnployers/whatever resolver more than they
trust the DNS server that the hotel DHCP pointed them at)?

(And yes, I *know* that "point at your employers DNS" works against a
threat model of "local provider is an idiot" and fails against "local
provider is willing to spoof replies from other DNS servers")
