General configuration
MAC address
Enter a MAC address in the following format: xx:xx:xx:xx:xx:xx
IP address
If no IP address is given, one will be dynamically allocated from the pool.
Description
You may enter a description here for your reference (not parsed).
IPv4 PXE configuration
  These IPv4 settings are usually only needed with PXE booting and for some VoIP phones. They can usually be left empty. These settings (if provided) will override any values specified for the whole pool. These settings are ignored for IPv6 addresses.
Next server
Specify the server from which clients should load the boot file.
Filename
Specify the name of the boot file on the server above.
