# IP address: Each hfi interface should be assigned its hostname and IP address.
# hostname should be resolable from either /etc/hosts or name
# resolution, with format: <nodename>-hfx
# netmask: Netmask is hardcoded in this script. You have to manually modify it
# if it doesn't meet your requirement.
