Let me correct myself here: my Gentoo boxen behave like this. A WinXP that I tested for this purpose does not. It comes up with the APIPA address and when a router becomes available in the network later on, it readily obtains a dhcp address and drops the APIPA. Any idea how to configure Gentoo to do the same? > I was also wondering what kind of useful purpose this would serve.

I am guessing that it is a way of getting two computers talking to each other when they find themselves connected, but without a router? -- Regards, Mick
