I noticed that the Oracle installation prerequisites check does not require you to have a loopback adapter when you have a DHCP address, but the installation documentation says it is required.  Why do you need a loopback adapter.

Oracle really likes a static IP address for a lot of its internal configurations.  you not only need a loopback adapter but if memory serves, it must be the first NIC listed.

Oracle is pretty dumb when it comes to networking.  When if needs to talk to the network, it grabs the first NIC available form the list and tries to use it.

It also prefers if for external reasons as well but those issues can be solved.
