If you'd like to prefer #IPv4 over #IPv6 (without fully disabling v6) on a #Linux machine, check out /etc/gai.conf.

I don't really understand the rules it contains, but at least on my #Debian machine, it's pretty helpful in explicitly saying:

"For sites which prefer IPv4 connections change the last line to `precedence ::ffff:0:0/96 100`"

And in case you're wondering why I'd do that: My IPv6 uplink is currently significantly slower.

Yes, I'll work on this. No, not tonight.
