Some initial issues with setting up Domain Mapping...

Hello,
I'm setting up a new multisite network and I've run into an issue. I'm going to wait the 48 hours.. but my question is: Is there anything else that needs to be done in the Domain mapping process, besides setting the A-Record? I did all that, but I'm not sure how to pull the domains into the network... 69.89.27.227 is the Server IP.
http://www.immoamerica.com is the root domain.

Trying to map:
immoamerica.es --> spain.immoamerica.com
immoamerica.ch --> switzerland.immoamerica.com
immoamerica.at --> austria.immoamerica.com
immoamerica.it --> italy.immoamerica.com
immoamerica.fr --> france.immoamerica.com

Any pointers on these first setup steps?

Thanks!
Ben
