  2. configure a Dynamic DNS in this account
  3. install a software client on your computer that will automatically update the hostname (DynDNS Updater for Windows or Mac, ddclient or inadyn for Linux)
  4. or you can also configure your modem if it supports DynDNS (NeufBox, …), then you don't need to install a client.
