I would like to know if there is one or if one could be made to update host IPs for DDNS hosted boards. I run my site from home and am on DDNS. When my IP changes I end up having to delete my boards and start from scratch. I don't like doing this. We need a utility that will update the IP address for everything from the localhost.
I don't know fo a tool for this but you can use repair-settings.php to change the paths when this happens.
What is repair_settings.php? (http://www.simplemachines.org/community/index.php?topic=18096.0)
Just set up your board using your dynamic name.
Then you use an updater provided by the service you use (either dyndns or noip).
