Do mean under the heading 'Testing/Debugging dynamic DNS update' ??

That command doesn't populate anything!

What network are your AD clients on '192.168.0.x', 192.168.122.x' or

I take it from the above, that your clients are on the '' 
network. Adding the lines you referred to, just makes samba connecting 
only to the interfaces that you have specified, also the records were 
added at provision not by the samba_dnsupdate command.
