I moved my Master/slave database architecture to Amazon RDS and everything works fine.
But I have a slave out of the RDS service which should keep sync with the new Master server, to do so I have to point my DB domain name master-db.myawsserver.com on the Master (RDS) private address IP.
AWS console didn't provide this information and I am connected directly to the MySQL database.

RDS instances can change their IPs unexpectedly, so they should not be used nor are they provided in the console or API (although you can technically
digfor them). The DNS endpoint provided in the AWS console will resolve to the internal IPs from within Amazon's network.
