Dynamic IP with TLDs
Got a web server on your machine, want a top level domain name, but your IP is dynamic? Well, easy solution is to sign up with a dynamic IP service like DynDNS. Once you’ve done that, add a CNAME entry onto your dns name server that references the subdomain (www or @ or whatever) to point to your dyndns name, like so. Of course, you need to have access to your name server zone file.
