Don't really care about ping outputs.  You are asking about name 
resolution with your bind server.  I don't care about ping because it 
uses some methods that are outside of DNS.  Like checking your hosts 
file and adding the search domains.

I will only comment on DIG outputs.  NSLOOKUP is better than PING, but 
does not post as much diagnostic output as DIG.  So when 
troubleshooting, DIG is the best option.

You are right in that you only need one host at to update 
your ip address, but you want to have two different websites.  The 
proper way to do that is with CNAME entries pointing to the host you are 
updating at connect time.
