# This is a basic configuration for the Kea DHCPv4 and DHCPv6 servers.
# Subnet declarations are commented out and no interfaces are listed.
# Therefore, the servers will not listen or respond to any queries.
# The basic configuration must be extended to specify interfaces on
# which the servers should listen. Also, subnets and options must be
# declared.
