Well, this is OS-dependent. On most Unix-like systems, it's done with an
ifconfig command in one of the /etc/rc scripts. I don't know about Mac OS X.
The closest thing I have is an ancient NeXTSTEP system in which there's this
command in /etc/rc.boot: "ifconfig lo0 127.0.0.1 up"
Of course, the name to address and address to name mappings for this IP
would be in /etc/hosts and/or in the DNS server's tables.
