Potentially, but we need more details.  What protocol is it? SPI? do you have the datasheet for it or a link to the website that it is on?  Without knowing more details we can't really help.

No, potentially it's Arduino compatible depending on what hardware it has.

It uses the microchip® enc28j60 chip and implements SPI so you can hook it to the Arduino. 

Unlike the Wiznet-based shields you will have to implement a TCP/IP stack in software if you want one.

Strongly opinionated, but not official!

If you're trying to save money vs the official Ethernet Shield, you might want to look at the existing Wiznet modules:
http://shop.wiznettechnology.com/Sub_Modules/en/product/product_list.asp?cateid=50
They're nearly the same price as many of the ENC28J60 modules (cheaper than the one you mention), have a lot more intelligence, and are software compatible (assuming they are connected properly) with the official ethernet shield.

I didn't see the price for the enc28j60 module that started the post. I've done a tutorial about using a similar device which cost me about $25 (GBP14.35 inc postage from  UK to UK).

The tutorial creates a webserver which presents a page with two buttons: "LED On", "LED off". The control an LED on the Arduino. The page also reports the reading from a light sensor which the LED shines upon.

For the next two hours or so it may not be continually up, as I am doing some work on improving the software, but it will be mostly up.

Hehe, blinky LED.
There's something quite satisfying about knowing there's a physical thing on the end of that webpage that you're controlling smiley
