Best practice for Windows integrated DNS zones in same forest

May be someone can answer this.

I have a windows environment with a single forest and several locations, each location having DNS servers integrated in AD.

My question is do I have to add only one DNS server or do I have to add all of the DNS servers into IPAM ?

Are there any advantages in adding all of the DNS servers in the forest since they share the same information ?

Thanks in advance for your feedback

You can get by with one. However, there are replication delays in AD integrated DNS zones, so it could be advantageous to add a DNS server from other AD sites to IPAM. The default inter-site replication interval in AD is every three hours. You can crank your replication intervals down to as little as 15 minutes too though.
