I expect people asking questions of other users to provide the commands 
they want the information from.

Nobody claimed to have an education in the topic. We just commented on a 
symptom. You, who claim to be the expert, is who has to ask the proper 
questions.

Don't be uppity.

It just is a perceived fact. On some machines, if an application gets 
back from the system a list of addresses to try, and tries IPv6 first 
when there is no actual IPv6 internet connectivity, there is a small 
delay waiting for the request to fail, and then try the next address in 
the list.

It doesn't happen to me currently, so asking me to provide information 
is pointless. But it has happened to me in the past. And I know because 
the software complained of no route or something.
