OpenDNS Updater: A Free And Easy Way Update IP Changes
OpenDNS Updater is a small AppleScript that helps keep your dynamic IP information up to date on the OpenDNS website. OpenDNS, which we’ve raved about before, is an alternative DNS server to replace the often sluggish ones your ISP uses. Not only is generally faster than your ISP’s DNS server, it allows you to do cool stuff like maintain a dynamic IP address so you can access your always-on machines from anywhere using remote desktop software.
But one of the problems with dynamic IP addresses is that you need to update servers with your actual IP. How often you need to do that depends entirely on how often your ISP changes your IP address, and who wants to keep track of that?
This handy AppleScript takes care of updates for you.
To use the AppleScript just double click and then enter your OpenDNS username, password, and the network name you want to update (be aware that this is case sensitive). Then you’ll see a popup window telling you your IP information was updated. If your IP hasn’t changed since the last time OpenDNS Updater ran, it will let you know that no update was necessary.
To automate the process you can either do something like make OpenDNS Updater a startup item in your account preferences, or you can set up crontab entry to run it periodically (it would be nice if there were a flag to turn off the no update info in some cases).
Of course for this to be useful, you need to be using OpenDNS and you must enable Dynamic IP Updating under the “Settings” tab on the OpenDNS site.
OpenDNS Updater is free, but it only works with Macs, if you know of an OpenDNS-specific Windows solution, post it in the comments
