the reason we using dynamic dns is to convert the hostname to dynamic ip. RemoteBoot will store the dynamic ip into part of the database, it wouldn't be able to detect when the ip has changed. it would be good to use a single field to capture HostName or IP address. When user inserted a hostname, it should run ip address lookup whenever user select "Boot". rather than force user to click on Edit>"Convert hostname to IP" manually before they can click on "Boot" anyway, is a good tool.
