What Are Some Use-Cases For Dedicated IP Address?

Just recently I came to the realization that a Dedicated IP is very useful if you are a website owner (for restricted access), a gamer (in case of hosting dedicated servers), a community person (who's participates in different communities). Besides these, what other use-cases do you think dedicated IP can be beneficial?

  • Clients need to find servers, so servers need fixed IP addresses.

    Remote access is a service, so if you want to enable a SSL Client VPN capability, UTM needs a fixed address for offering that service.

    Home users are generally offered only dynamic IP addresses, because the ISP assumes that you are only performing client functions.   Generally, if you want a fixed address, you have to switch to a business account.   Many ISPs block port 25 on dynamic IP addresses, and possibly other ports as well, to enforce this policy.

    Dynamic DNS provides some workarounds to this, but the principle remains.   For example, email RBLs will blacklist dynamic IPs on the assumption that if a dynamic IP is running a mail server, it is probably an infected machine.

    Business that are offering any server function to the internet will buy a fixed IP.
