Albeit you can adjust configuration to allow more records in one place 
it is not recommended. Doing so opens possibility of DoS attacks.

In short yes. You will also get better performance if you spread out the 
records across multiple _names_. Besides other things size of single 
resource record _set_ is limited to 64 kB so putting all records onto a 
single node would eventually create issues even without this limit.

I hope it helps to understand the situation.
