The Identification page allows you to specify various name parameters for your FreshTomato device.
Router Name: Here, enter a nickname for the FreshTomato device for your own reference.
The router name will display on the Overview page and in the title of the router's web interface pages. This is not a TCP/IP hostname. It does not register the device or help resolve it on the network. The hostname field is the TCP/IP hostname and serves those functions.
Hostname: Here, you can specify the TCP/IP hostname of your FreshTomato device.
This name will be registered on an IP network for functions such as outgoing DHCP lease requests, local DNS resolution, and NetBIOS name resolution for SAMBA filesharing. It is also used extensively in the log, which helps with router identification when you have multiple routers reporting back to one log server.
Domain Name: This field sets the TLD (top-level domain) name of your router's internal DNS server. It defines a namespace for your LAN.
If you enter a name that conflicts with a registered TLD on the Internet, the local network will take priority (avoid using, “.com” or “.org”). For home networks, this should usually be set to something like “local” or “lan”. If this field is left blank, there will be no local DNS resolution of devices on the LAN except from devices that support/are running mDNS.
For example, let's say you if you set the Domain Name to “local”, the Hostname to “Router”, and you have an IP camera on your LAN with hostname “Camera-32DA” (similar under “Name” on the router's Device List page). Typing “router.local” into a browser would open your router configuration page. Entering “camera-32da.local” would open your camera's webpage. Entering “\\Router” into Windows File Explorer would show you a list of objects shared by your router's SAMBA (if enabled).
