the DAG will register the "live" IP in the DNS depending on which one is active, there is no need to register it manually

There was a record created before in DNS for the DAG so can I delete that record and will the DAG recreate the new DNS record entry.

yes as long as your DNS is on windows and supporting dynamic updates (which should be the case in 99% of the case) you can delete the DNS record and it will be created again

Not necessary to manually add a DNS record for your Exchange 2010 DAG.

Make sure that the NICs for the replication network, however, do not have the option enabled to "Register this connection's addresses in DNS" so they do not automatically create a DNS entry.

Can safely delete the record that is currently there?
