Project description

This Ethernet shiled library does not come with DNS support out of the box meaning we cannot used to access the website we need by its simple URL (like?http://www.14core.com). We need to have access the site though an IP address. For instance 192.168.10.100, 200,188,122,145 and you can actually access.
