DNS record for multiple DCs

I uinderstand the SRV records and A records for our domain controllers. What we are seeing is that we have a single A record for the domain itself (example.com) that points to the ip for controller1.example.com. What we’re trying to figure out is if for redundancy’s sake we should round-robin it so that the domain record points to the ips for controller2, controller3 and so forth.

Current:
example.com 86400 IN A 192.168.1.1

Should we have:
example.com 86400 IN A 192.168.1.1
86400 IN A 192.168.2.1
86400 IN A 192.168.3.1
Thanks for any help
