  3. You can't do DNS with a dynamic IP address. That makes it harder to do stuff with a server as now instead of remembering you have to remember or something like that, not to mention it will change frequently (at most places).

    Also, I know of some services (that use ssh and https) that will restrict access based on IP, which pretty much rules out having a dynamic IP.

    I do run servers with dynamic IP (and even behind a firewall), but if you want it to be used by the masses then you definitely need a static IP.
  4. Clearly your address is dynamic, because the host ID changes!
    If you run server processes in your computer, clients cannot connect to it by specifying the IP address. You would need a DNS name.
  5. This is not right. You can run servers with a dynamic IP address. Its just that your address might change making it incovenient for public use.
  6. That's what I meant, actually. Non-convenience.
