You (as others have) might some day deploy separate actual servers
behind a single logical host with multiple IP addresses, and then
testing just one of the IPs is not enough.  Of course, if you have
a load balancer, it gets even more fun.

Some folks fail the tests for a couple days and then succeed, and
then later fail again, because they have two machines behind a
load balancer with different certs, and TLSA records for just
one of them.  Notices appear to be ignored...

You're quite welcome.  I try, and it helps, but only so much, the rest
is up to the operators, who sometimes have enthusiam for deploying cool
things, than for keeping them well oiled. :-(
