DHCP IP Helpers

Hi there,

I have a secondary location that was spun up with a new DHCP cluster. Each location has 2 dhcp servers acting in a load-balancing failover cluster. Currently, I have the two dhcp servers at the primary location as my helpers (ex: 10.0.1.1, 10.0.1.2) and will be needing to add the secondary location servers (ex: 10.0.2.1, 10.0.2.2). I read in this MS doc that if i use broadcast IPs, it would allow me to relay to all 4 servers. Would you all recommend this?

Solution?:

10.0.1.255

10.0.2.255

If you have a better solution overall, I'm def open to it.
