There may be some mix-up between CentOS and Debian conf on that page,
I'll double check tomorrow.

As far as NetBIOS is concerned, just try to kill it, it will be better
for humanity :-)
I'd say that the IP address is the best thing to have in the log as it
is the only reliable information the DNS server has when it receive a
request (if we put aside UDP source ip spoofing...). You can then
post-process the log in a SIEM with information from DHCP and reverse
DNS. But even then DHCP and reverse DNS cannot be completely reliable
unless you add in some 802.1x and strong authentication in the mix.
