# Set the DHCP server to authoritative mode. In this mode it will barge in
# and take over the lease for any client which broadcasts on the network,
# whether it has a record of the lease or not. This avoids long timeouts
# when a machine wakes up on a new network. DO NOT enable this if there's
# the slighest chance that you might end up accidentally configuring a DHCP
# server for your campus/company accidentally. The ISC server uses the same
# the same option, and this URL provides more information:
