Using DDNS and IPv6 for secure node connectivity


Hello folks,

Does anyone know whether the combination of Dynamic DNS and dynamic IPv6 works for secure node operation? How, if at all, does the externalip parameter in the zen.conf file fit into the picture? Thanks.


If your IP is truly dynamic (most IP providers rarely actually change - apart from mobile providers who can’t lock a physical location).
Your DDNS provider will automatically update your DNS records, but as you point out you will need to re-start zend with an updated zen.conf
In reality - this will ONLY be an issue for IPv4
So the best work-around is to use an IPv6 tunnel and set IPv6 only in your setup as this address will be static regardless of your IPv4 changes (hurricane electric 6over4 has an update utility)
