TCP/IP uses it to function. Although not mentioned in RFC793 (as far as I
can see), it is utilized for many things. Siebel (actually, Actuate) uses
it. The SP 'SDR' uses it.
Run 'iptrace -e -i lo0 /tmp/iptrace.out' and let it run for a few minutes.
Kill the iptrace PID.
Then run 'ipreport /tmp/iptrace.out > /tmp/ipreport.out'
Do a more on /tmp/ipreport.out and you'll see what is using it.

What does it do? I wouldn't do it on a production box, just playing.

Why would you try to delete it ? Lots of things use the loopback device.
It is a fundamental part of the local machine's TCP/IP stack.

I guess I'm not completely sure what the function of the loop back, lo0 is?
AIX won't let me delete it, so its being used.
My HTTP Server has high lo0 loop back activity? Nmon option 'n' is showing
395.0 Peak->Recv and Trans for Lo0. HTTP login times are timing out, on
occasion.
Any thoughts and thank you!
