This is a little suspect to me:

(from Deutsche Telekom)

thomas at eee-box:~> ping6 www.xbox.com
unknown host
thomas at eee-box:~> host www.xbox.com
www.xbox.com is an alias for www.gtm.xbox.com.
www.gtm.xbox.com is an alias for wildcard.xbox.com-c.edgekey.net.
wildcard.xbox.com-c.edgekey.net is an alias for wildcard.xbox.com-c.edgekey.net.globalredir.akadns.net.
wildcard.xbox.com-c.edgekey.net.globalredir.akadns.net is an alias for e2820.dspb.akamaiedge.net.
e2820.dspb.akamaiedge.net has address 92.122.27.141
e2820.dspb.akamaiedge.net has IPv6 address 2a02:26f0:3:181::b04
e2820.dspb.akamaiedge.net has IPv6 address 2a02:26f0:3:186::b04
e2820.dspb.akamaiedge.net has IPv6 address 2a02:26f0:3:185::b04

the same at a different site:

(from LRZ/DFN)

thomas at diener:~> host www.xbox.com
www.xbox.com is an alias for www.gtm.xbox.com.
www.gtm.xbox.com is an alias for wildcard.xbox.com-c.edgekey.net.
wildcard.xbox.com-c.edgekey.net is an alias for wildcard.xbox.com-c.edgekey.net.globalredir.akadns.net.
wildcard.xbox.com-c.edgekey.net.globalredir.akadns.net is an alias for e2820.dspb.akamaiedge.net.
e2820.dspb.akamaiedge.net has address 23.9.212.150
e2820.dspb.akamaiedge.net has IPv6 address 2a02:26f0:3:185::b04
e2820.dspb.akamaiedge.net has IPv6 address 2a02:26f0:3:183::b04
e2820.dspb.akamaiedge.net has IPv6 address 2a02:26f0:3:186::b04
thomas at diener:~> ping6 www.xbox.com
unknown host
thomas at diener

But sometimes it works.

Is it an resolver-problem, or is the network not stable, or is it PEBKAC?

Can anybody confirm this problem, or suggest a better test?
