[sofiasyria]

After recent changes for www.suse.com DNS round robin, it is not a
suitable domain for testing the dns server set-up of test scenario
yas2_cmd.

@tonyyuan1 is changing the domain from www.suse.com to www.opensuse.org acceptable for the resolution check?

You can see from the screen shot above that the return of first "dig" (dig www.suse.com +short) was 13.244..
the second "dig" (dig @localhost www.suse.com +short) was 99.86...

Something interesting:
I connected to a machine in office via vpn then dig www.suse.com. I got :
d3m3mf8gecrp5l.cloudfront.net.
13.224.195.3
13.224.195.58
13.224.195.47
13.224.195.105

I disconnected vpn and switch to my home ip address, digging it again. I got:
d3m3mf8gecrp5l.cloudfront.net.
99.86.3.62
99.86.3.70
99.86.3.14
99.86.3.26
I seems that digging from different IP addresses get different results.
