I am hosting my own site with Small HTTP server, I have dial-up
(dynamic IP) and it changes everytime I reconnect. I use BalidDNS to
update it, but I want a DNS updater that automaticly updates everytime
I connect to the internet.

I also want a service that allows me to add sub domains my current sub
domain, (I use dynds) I have my subdomain zentec.ath.cx, I want to add
sub domains it it (such as mac.projects.zentec.ath.cx). Is there a
service that does that?

Also, a update client that can update every certain amount of time.
