+== Steps for allocating an IPv6 address ==
+
+The IPv6 process is much more manual, and not directly managed by puppet.
+
+=== find a free IPv6 address ===
+
+first, list all claimed IPv6 addresses by searching in :
+
+{{{
+0 mfpl-puppet$ git grep 'gateway.*->.*:'
+manifests/nodes/production/che.pp:# mayfirst::m_interface::set { "2001:470:1:116::7/64": gateway => "2001:470:1:116::1" }
+0 mfpl-puppet$ 
+}}}
+
+Note that the lines are commented out (with a `#`).  this is as intended, they're still allocations, because puppet isn't dealing with IPv6 at all yet.
+
+Then choose a free one.
+
+=== assign it to the host manually ===
+
+place the appropriate stanza in a new file in `/etc/network/interfaces.d/` on hosts that use `ifupdown`, or in a `/etc/systemd/network/*.network` file on hosts that use `systemd-networkd`
+
+=== claim it in puppet ===
+
+remember to add a commented line in the appropriate puppet production file corresponding to the host!
