Some days ago, my friends asked me what is the equivalent of IPv6 link-local address fe80::/64 in IPv4. Link-local address is auto-configured in the absence of router or DHCPv6 server. In IPv4, we have 169.254.0.0/16 random addresses assigned to a NIC if it can not find any DHCP server. Most importantly, hosts with 169.254.X.Y can communicate with each other since they are in the same /16 subnet.
However, there should be one difference, only Windows and Mac stations support 169.254.0.0/16. While in IPv6, all OSes must support the link-local address and this should include iPhone OS and Android.

Your friendly blog stalker back again.
Some extra info for your post, it's called APIPA or / IPv4LL, and is also seen on Linux systems with the ISC DHCP Client, but most distros ship with the dhcpcd having the -L flag which disabled APIPA/IPv4LL.
Just a few cents from me. :)
