# This is an example configuration file for D2, Kea's DHCP-DDNS processor.
# It supports updating two Forward DNS zones "four.example.com" and
# "six.example.com"; and one Reverse DNS zone, "2.0.192.in-addr.arpa."

# --------------  Global Parameters ----------------
#
#   D2 will listen for update requests for Kea DHCP servers at 172.16.1.10
#   on port 53001.  Maximum time to we will  wait for a DNS server to
#   respond to us is 1000 ms.

#
# ----------------- Forward DDNS  ------------------
#
#   1. Zone - "four.example.com.
#      It uses TSIG, key name is "d2.md5.key"
#      It is served by one DNS server which listens for DDNS requests at
#      172.16.1.1 on the default port 53 (standard  DNS port)
#
#   2. Zone - "six.example.com."
#      It does not use TSIG.
#      It is server by one DNS server at "2001:db8:1::10" on port 7802
