Edited ifcfg-lo (already commented out all the IPv4 address lines, and still was getting 127.0.0.1), added the onboot=no and the IPv6 commands, restarted network and got the message: RTNETLINK answers: File exists I rebooted and saw this message when the loopback was brought up (even with the onboot=no command!). I disabled iptables (it started before loopback). Still betting ipv4. Started looking through /var/log/messages and see that there is a line: kernel: NET: Registered protocol family 2 Hey, wait a minute, I have in my /etc/modprobe.conf: alias net-pf-2 off WHAT GIVES HERE???? I also see messages about starting IPv6 over IPv4 tunneling driver. Why? I don't need it here for this test? So it looks like there is a BUNCH of network stuff that runs even if you don't ask for it (great defaults, I guess), and no documentation on turning the stuff off.....
