+gluon-464xlat-clat
+==================
+
+This package provides the kernel module and functionality required to support
+ipv4 clients on an ipv6-only backbone.
+
+Assumptions
+-----------
+
+* Clients will be given IPv4 addresses by a dhcp daemon that runs on each node.
+  gluon-ddhcpd is a great choice for this.
+* There is a component on the network that does plat on the default network
+  64:ff9b::/96. https://github.com/FreifunkMD/jool-docker.git can do this.
+
+Limitations
+-----------
+* When roaming, clients will experience temporary loss of IPv4 connectivity
+
+site.conf
+---------
+
+clat_range : mandatory
+    - infrastructure net (ULA) from which a /96 clat prefix will be generated.
+    - This must be a /48 prefix.
+    - This can be the same for each community and is pre-registered at https://wiki.freifunk.net/IP-Netze#IPv6 as part of fdff:ffff:ff00::/40
+
+Example::
+
+  {
+	clat_range = 'fdff:ffff:ffff::/48', 
+  }
+
