  • Auto Host List Download
  • Runs When Logged Out
  • Open Source


The installation will complete and the application will ask for your account information. After your username and password have been authenticated you will be shown a list of hostnames. Select the hostnames that you would like updated to the IP address of your computer.

UBUNTU USERS: You may install this with the apt-get command, see this guide.

NOTE: You must add hostnames on the website first before you can have the updater update them.
