No, we do not directly support this, but there are free and cheap services available.
DynDNS.org,
No-IP.com and
ChangeIP.com are some alternatives.
In order to use such services, you have to set up a DNS pointer for your domain (e.g. www.example.com) to the address assigned by the provider.
Note! The domainname itself without "www" or any other prefix cannot be such a pointer, that is technically impossible.
To handle web pages directly with http://example.com/
you must therefore use www forwarding from http://example.com/
to http://www.example.com/
and let www.example.com be handled dynamically as in the first example below.
