If a DHCP server is not reached or leased configuration fails, the computer
uses APIPA (Automatic Private IP Addressing) to automatically configure
TCP/IP. When APIPA is used, Windows 2000 determines an address in the
Microsoft-reserved IP addressing range from 169.254.0.1 through
169.254.255.254. This address is used until a DHCP server is located. The
subnet mask is set to 255.255.0.0.

The range of IP addresses (from 169.254.0.1 through 169.254.255.254) used
for APIPA is reserved by the Internet Assigned Numbers Authority (IANA). Any
IP addresses within this range are not used on the Internet.

With Windows 98, Microsoft TCP/IP provides a new mechanism for IP
addressing, called automatic private IP addressing. If you have a small
network, without a DHCP server, you can assign a unique IP address to your
network adapter using the "LINKLOCAL network" IP address space. LINKLOCAL
network addresses always begin with 169.254 and have the following format:
169.254.X.X

The consequence of this is that each machine will select a random IP
address. Hence Kevin's problem of unable to ping and 'arp who-has' messages.

Uh, do you happen to know anywhere that this is actually used?
