I would want to know why. Almost any computer today 'talks to itself' using the loopback. Linux is no exception. HMC is Linux.

While working with a serviceable event on my HMC they had me send in some

HMC Management
Network Settings
Change network settings.
Select eth0, Details

Change from:

Specify an IP address
TCP/IP interface address: 127.0.0.1
TCP/IP interface network mask: 255.0.0.0

to:

No IPv4 address

I wasn't really given a reason why. Should I just do it?

eth3 is the one really in use.
