This will allow you to use the hostname for various things, without the need to know your dynamic IP address, assigned by your ISP.
You need to create an account and pick a hostname (not already in use)
Then download the client and fill in the details
It will then update the hostname with the IP address
It can take around 5 minutes between changes of IP to update the DNS
Please naviate to the login and download pages via the menu on the left side
This is currently a free service for 2 host names, unless we manage your DNS record.
