The Identification page allows you assign names to Tomato device, for your own reference, and as an IP host.
Router Name: In this field you can enter a nickname for your Tomato device for self-reference. The router name will display display on the Overview page, and in the web page title for the router's web interface. This is NOT a TCP/IP host name-it doesn't register the device or help resolve it on the network. The next field is for that.
Hostname: Here you can enter a TCP/IP / Netbeui hostname for your Tomato device. This name will be registered on an IP network for functions such as DNS resolution. It also acts as a Netbeui host name, so it helps with filesharing.
Domain Name: TBD
