B Rog writes "Cisco, Atmel, and the Swedish Institute of Computer Science have released uIPv6, the world's smallest IPv6 compliant IPv6 stack, as open source for the Contiki embedded operating system. The intent is to bring IP addresses to the masses by giving devices such as thermometers or lightbulbs an IPv6 stack. With a code size of 11 kilobytes and a dynamic memory usage of less than 2 kilobytes (yes, kilobytes!), it certainly fits the bill of the ultra-low-power microcontrollers typically used in such devices. When every lightbulb has an IP address, the vast address range of IPv6 sounds like a pretty good idea."
