+NAME
+----
+cdist-type__ungleich_unbound - unbound server deployment for ungleich
+
+
+DESCRIPTION
+-----------
+This unbound (dns resolver and cache) deployment provides DNS64 and fetch
+answers from specified upstrean DNS server. This is a singleton type.
+
+REQUIRED PARAMETERS
+-------------------
+dns64_prefix
+  IPv6 prefix used for DNS64.
+
+forward_addr
+  DNS servers used to lookup names, can be provided multiple times. It can be
+  either an IPv4 or IPv6 address but no domain name.
+
+OPTIONAL PARAMETERS
+-------------------
+interface
+  Interface to listen on, can be provided multiple times. Defaults to
+  '127.0.0.1' and '::1'.
+
+access_control
+  Controls which clients are allowed queries to the unbound service (everything
+  but localhost is refused by default), can be provided multiple times. The
+  format is described in unbound.conf(5).
+
+BOOLEAN PARAMETERS
+------------------
+disable-ip4
+  Do not answer or issue queries over IPv4. Cannot be used alongside the
+  `--disable-ip6` flag.
+
+disable-ip6
+  Do not answer or issue queries over IPv6. Cannot be used alongside the
+  `--disable-ip4` flag.
+
+EXAMPLES
