@dfitzmau asked a couple questions in slack, answering here for simplicity
What could happen if one does not set the same IP address?
this depends on their configuration. if they are only using a single NIC, then it should work as expected. But, if they have multiple NICs, then it is possible that the CCM would choose the wrong NIC because it would be using the operating system ordering.
If they want to switch to a multiple NIC environment, it's a case of just updating the IP address for the CIDRs (they must be different)?
that's correct, although since this is a cluster-wide configuration they will need to ensure that the machines have the proper NICs and configurations as well. (eg do all the nodes have NICs on the proper CIDRs, etc).
I found a multi-NIC DHCP DNS race condition on baremetal, OCPBUGS-35317.
I haven't reproduced on vSphere, but the issue is that we don't have a way to select which DNS is used in resolv-prepender.sh. With Multi-NIC we could select a network that doesn't have access to quay.io.
So maybe we need to adjust the Quay.io note like
All NICs must have access to Quay.io to obtain the packages that are required to install your cluster.
Thanks, Ross. I'll hold this PR until https://issues.redhat.com/browse/OCPBUGS-35317 is closed.

The branch/enterprise-4.17 label has been added to this PR.
This is because your PR targets the main branch and is labeled for enterprise-4.16. And any PR going into main must also target the latest version branch (enterprise-4.17).
If the update in your PR does NOT apply to version 4.17 onward, please re-target this PR to go directly into the appropriate version branch or branches (enterprise-4.x) instead of main.
