. . . <snip> I did not find the right RFC, but at least Microsoft and Apple dynamically assign 169.254/16 IP addresses to DHCP clients when their DHCP-requests time out (they call it "Plug-And-Play Networking").

I didn't found it in RFCs but in some other publications -- e.g: Automatic addressing without DHCP: When a Windows 2000 client configured for automatic addressing comes up, it tries to obtain an address from a DHCP server. If that attempt fails, the client tries to ping the default gateway defined in its current lease. The client continues to use the existing lease if the ping succeeds and then checks for a DHCP server every five minutes for a new lease. If the ping fails, the client assumes that DHCP services are not available on the network and automatically assigns itself a non-conflicting IP address in the private address range 169.254.n.n (subnet 255.255.0.0). In other publications is declared, that M$ has especially reserved an address (169.254) only for those cases, that no DHCP-Server is reachable or no IP-Address is given to the host (e.g. in small networks). The host makes a broadcast with an address from the range and -if nobody answers- allocates that address to itself! For this I would search too for a notebook or a pc (removed or with 'standard-installation). AFAIK only computers with W98/2000 (/Me??) are concerned.
