Well you "ip addy" doesn't since you have a DNS doing it for you. Assuming you are using dyndns because you have a dynamic IP you shouldn't worry about what your IP is ;)

And to bind a specific IP to your DNS name, well that should be done by your registrar (dyndns.org). The rest is done by ensuring that port 80 is open and that apache is running, that's it. When people access your box:
http://bennetm.kicks-ass.org OR
http://1.2.3.4 (which is actually your IP you get from typing "ifconfig")
they should get your DocumentRoot index.html (or variation of it)

Cool

Ok thanx so i dont need to add my ip addy anywhere, so under virtualhost i should make a NameVirtualHost like this <Virtualhost 1.2.3.4> ServerName bennettm.kicks-ass.org ServerPath /var/www/html </VirtualHost>?? i put this in httpd.conf???? or in vhosts??? Thanx
