# Here you find a description on every parameter supported
# and used by ddns-scripts and corresponding LuCI application
#
# Inside your ddns configuration file (/etc/config/ddns)
# you might not find some of below described options.
# This is because you don't need to define options
# if using there defaults. The LuCI application will delete
# options that configured to there default values.
#
# If you have a working ddns configuration from old ddns-scripts (Version 1.x)
# everything will function the same with new scripts
# without any changes to the configuration.
#
# If you like to use this file for your configuration then
# use a copy, because the used software to modify the
# configuration files will throw away all empty lines
# and those starting with # (comments).
