So, in the above, the records preceded by # are those from our AXFR from
ns1.balug.org., whereas those without leading # are those looked up on
ns1.dreamhost.com., without recursion - and just asking for answers,
except in the case of NS records other than balug.org. itself (notably
subdomains thereof), we instead look for authority rather than answer.

"Of course" we can't do an AXFR from ns[123].dreamhost.com., unfortunately.
So, that doesn't tell us any records that may be there and not found  
for balug.org.
under ns1.balug.org.  However, I can check that under DreamHost.Com's  
eweey GUI
web interface thingy - and I do, most notably when I see their zone serial
number change for balug.org. or otherwise see any data changes in their
hosting of the zone.

It's also a bit more clear in master zone file for balug.org. on  
ns1.balug.org.,
as commenting clearly breaks out what mandatory included DreamHost.Com  
provided
stuff we can't change (at least so long as it's hosted by DreamHost.Com),
what bits we've added and do control (possibly excepting TTLs), and also
notes those that are explicitly different for some necessary or other darn
good reason.
