[ale] Multi-label names

[Lightner, Jeffrey]

Does it run any better if you turn off systemd-resolv (systemctl stop systemd-resolv)?

What is in your /etc/resolv.conf on the two servers?

I am having a problem after an upgrade to ubuntu artful. If I do a host lookup for a non-existing, unqualified host name, it takes a long time to error ot. Say I have a host named spock. I can say, "host spock" and that comes back instantly. If I say, "host sopck" or some other typo, it takes like 10 seconds and I get this:
$ host -v sopck
Trying "sopck.example.com
Trying "sopck"
;; connection timed out; no servers could be reached

On an old machine, I get this:
$ host -v sopck
Trying "sopck.example.com
Trying "sopck"
Host sopck not found: 3(NXDOMAIN)
Received 98 bytes from 192.168.0.1#53 in 0 ms

I see that on the ubuntu/artful machines, I am running systemd-resolv (through no fault of my own). It's listening on 127.0.0.1 and caching DNS queries. So trying to read the man page for systemd-resolv, I keep coming across the term "multi label names". I never heard that term before, don't know what it means, and it appears to be ungoogleable.

Any advice on the original problem or on the meaning of that term would be appreciated.
