Network DHCP	If DHCP is enabled the VBrick must get it's IP address and Subnet
	Mask from the DHCP server. If the DHCP server supplies the

Subnet Mask	Subnet mask for the VBrick Ethernet IP address.
Gateway IP	Gateway IP address for communicating across the Ethernet segment
	attached to the VBrick.
Host Name	On Ethernet models, this is used for DHCP Client Host Name. The
	Host Name defaults to the Media Access Control address, a hardware
	address that uniquely identifies each node of a network. Host Name
	can be 18 characters maximum and the first character must be a letter.
	The remaining characters can be letters, numbers or hyphens.
