I just got this idea in my mind...
I can have say myhome1.dydns.com for free. However I have my own domain right now, say mydomain.com. My domain pointing to a linux server w/ cpanel managed by my self.
I really know about domains, IPs, nameserver, A record etc... but I dont have any idea to update my dynamic IP.
How can I use dynamic DNS service like dydns but using my own domain like myhome1.mydomain.com for free or any workaround like design small app tu update etc...?
Note that when I try to add domain in dydns, I need to buy either a domain, DNS service or email routing.
