This article is from a FAQ concerning SCO operating systems. While some of the information may be applicable to any OS, or any Unix or Linux OS, it may be specific to SCO Xenix, Open There is lots of Linux, Mac OS X and general Unix info elsewhere on this site: Search this site is the best way to find anything.
The kernel knows its own ip address, even in single user mode where TCP/IP is obviously not running. A machine in init state 1 will still respond to pings, for example.
So you'd think perhaps that's why you need to relink, but a little experimentation shows that even without relinking, a single user machine still responds to the address put in with netconfig.
Apparently, then, there is no reason to relink if you are just changing IP addresses- it works fine without it.
