+    <title>Using SSL distribution over IPv6</title>
+    <p>It is possible to use SSL distribution over IPv6 instead of
+    IPv4. To do this, pass the option <c>-proto_dist inet6_tls</c>
+    instead of <c>-proto_dist inet_tls</c> when starting Erlang,
+    either on the command line or in the <c>ERL_FLAGS</c> environment
+    variable.</p>
+
+    <p>An example command line with this option would look like this:</p>
+    <code type="none">
+$ erl -boot /home/me/ssl/start_ssl -proto_dist inet6_tls
+  -ssl_dist_opt server_certfile "/home/me/ssl/erlserver.pem"
+  -ssl_dist_opt server_secure_renegotiate true client_secure_renegotiate true
+  -sname ssl_test

+    <p>A node started in this way will only be able to communicate with
+    other nodes using SSL distribution over IPv6.</p>
