+ <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

+Eshell V5.0 (abort with ^G)
+(ssl_test@myhost)1> </code>
+
+ <p>A node started in this way will only be able to communicate with
+ other nodes using SSL distribution over IPv6.</p>
