The Arduino Ethernet Shield allows an Arduino board to connect to the internet. It is based on the Wiznet W5100 ethernet chip.

The Wiznet W5100 provides a network (IP) stack capable of both TCP and UDP. It supports up to four simultaneous socket connections. Use the Ethernet library to write sketches which connect to the internet using the shield. The ethernet shield connects to an Arduino board using long wire-wrap headers which extend through the shield. This keeps the pin layout intact and allows another shield to be stacked on top.

License Note: It looks like this shield is derived from the official Ethernet Shield (v4.0) design with some minor tweaks, so legally it is required to be under the CC-BY-SA 2.5 license with credit given to the original design. However, I could not find the design files, license info, or credit.
