Are you moving specific domain name Virtual websites to different IP 
addresses and also changing DNS IP addresses as well?
If you are, you will have to also change the Registrars DNS record 
information to point to the new DNS IP address. When moving virtual sites 
to different IP addresses, it may take a while to propagate. This might 
explain why you go to D.org and get A.com. I know when I move virtual sites 
to different IP addresses, depending on what DNS is used, it could take a 
couple of days to propagate and resolve correctly.
