I am attempting to set up the server at the moment, but I have a question before I begin about the network addresses used in the example. I am trying to set my server up behind a router and cable modem service. I don't have a static IP from my ISP and I'm trying to find a way to set one up for free. I'm going to register a domain name, but does that mean it is the name I should put in for the hostname (www.example.com)? But then I need to get a something that will update the IP address with where I register my domain if I'm unable to get a static IP from my ISP? And I should contact my ISP for DNS servers or can I just use the ones from article? And lastly how can I determine what gateway and netmask address I should be using? If anyone can point me in the right direction I would appreciate it.
