Fixed IP address vs Host

Hi everyone,


I have a question regarding Infoblox DNS/DHCP.
What is the difference between a fixed IP address and a host in Infoblox?
What I’m trying to understand is when we decide to fix an IP address and when we configure it as a host.
And when an IP is set as a host, does it behave like a fixed address and will not change?

Or when we create a host record, we’re not concerned with the MAC address at all, and the main goal is simply to assign an IP address to an FQDN?

I appreciate any guidance you can provide.

    A host record is a construct that allows the consolidated management of both DNS records (A, AAAA, PTR, and host aliases) and DHCP fixed addresses (FAs). The biggest difference between a FA and a Host from the DHCP perspective is that with a FA you can set more specific DHCP parameters (e.g., different DHCP option values) than you can within a host record. If your only concern is mapping a specific MAC address (or DUID) to an IP address, the host record is capable of doing that, just make sure the DHCP box is checked in the host IP address configuration.
