Howcan I host a website from my home machine? I havea DynDNS address so that even if my external IP changes, the machine is accessible.Lets say, for example, the machine is accessible at example.dyndns-home.com (this is a free service from DynDNS). I've registered a domain name for my website from GoDaddy. Let's say that domain name is example.comRight now, I've forwarded port 80 so I canenter example.dyndns-home.com from anywhere and I can see whatever I've hosted at my homebox.How can I make it so that, when I enter www.example.com, I see the same thing? I want to see what I host on my home machine out on the internet via example.com. 
I registered a domain name  how can I point it to my DynDNS host?
domains;dns
Add a cname record to the DNS record for your domain, pointing from www.example.com to example.dyndns-home.com. I've only ever used one domain registrar (not Godaddy), but they have a neat web interface where you can update the DNS record.Raw example:www.example.com.43200INCNAMEexample.dyndns-home.com.Working example is provided, at least using Google's nameservers.Edit (twice):If you wanted http://example.com to work too, you must add a second entry from example.com to example.dyndns-home.com. This might be done by forwarding @.example.com, I don't know if that's standard or not.
