# info: add dns domain

#
# The function adds DNS zone with records defined in the template. If the exp
# argument isn't stated, the expiration date value will be set to next year.
# The soa argument is responsible for the relevant record. By default the first
# user's NS server is used. TTL is set as common for the zone and for all of
# its records with a default value of 14400 seconds.
