Since Exchange 2013 SP1 on server 2012R2 you can now create IP-less DAG's. If you are on SP1 or later I would recommend creating IP-less DAG as this is now Application Layer availability. This is easier to setup and uses the Active Directory Configuration Partition to find where DAG members are.

You can use the below link for a full walk-through on how to setup Exchange 2013 DAG

When you use an IP-less DAG you do not need a DAG/Cluster IP for the DAG. You can still make sure that you have a Replicaiton Network in place so that it will use that for replication rather than production. If you do not have a replicaiton network it will use production by default.

if I have 10 databases do I have 5 active on 1 server and the other 5 active on the other
Active Active, no. Depending on the version of Exchange Standard or Enterprise you will be limited to 5 Total Mounted Database on a standard version of Exchange server. This means that if you are hosting replicatas from another DAG memeber then you are going to want to make sure that you only have 5 databases on a Standard installation of Exchange. You can have more and passive database but you can ONLY have a total of 5 MOUNTED database at a time.

So even thought you can have more malbox databases on a server if one of your DAG members fails and you already have 5 databases mounted it will not failover.

If you are using an Enterprise version of Exchange you can have up to 100 mounted mailbox databases.
