I have 3 primary hardrives, all have windows 7 on, which I sometimes rotate on this machine (so 3 versions of windows, the hardrive I have in is the one working (the other ones are on the desk,not connected)

Somthing about half the programs installed on hardrive 1, hardrive 2, hardrive 3, dont ask why lol.

When i rotate all 3 hardrives, does the Ip address change each time? (Same computer, same router.

    If you're using DHCP and shutting down and restarting each time, possibly depending upon your setup.

    To check, go to a command prompt and type in

    ipconfig /all

    Whether or not the ip changes is more a function of the network card and what ever network device (router, switch, modem) you have that issues (DHCP) ip addresses. A router with a DHCP lease option that doesn't expire will usually issue the same ip to the same computer every time based on the mac address of the computer's network card.

      the computer and the hard drives have nothing to do with
      the IP assigned when you go out on the internet.

      it depends on the company and the hardware that company
      gives/assigns to you.

      some companies (ISP) do assign you to a fixed IP 'group' and
      you will always be on that IP address when you are 'out'
      on the internet.

      then there are ISPs like Verizon which assign you to the least
      busy IP group available when your computer's router 'sees'
      your computer is active and seeks the internet. I am in south
      new jersey, and have seem my IP address geographically be
      as far north as white plains new york and as far south as fairfax
      viginia!

      the easy way to figure this out is to go to
      What Is My IP Address - Shows Your IP Address
      and note the address. close your browser, turn off/on your router
      and when you are back up? check you IP again. if it is different, then
      you have a company that rotates IPs, if not? then you have a fixed
      IP address.

    It depends on how you are connected to the internet. If you are connecting directly to a cable or DSL modem (only one computer in the house) and use DHCP (Dynamic Host Configuration Protocol) you will get an IP address assigned by that modem (which may actually be passing the IP from your vendor's server. However, over time this may change periodically. I've noticed with my connection (oceanic time warner roadrunner) they change the DHCP assigned IP my cable modem sees every day or two. It doesn't affect my computers because I run them connected to a hardware firewall/router. Many service providers change the DHCP assigned IP they give you fairly often to prevent you from running servers on a non-business account.

    If you have a local firewall or router to allow more than one computer on your cable or DSL account, you have two options. The IP address will be different than the vendor provides you because your router or firewall will do something called NAT (Network Address Translation). With DHCP, an IP is automatically assigned when you boot your computer. Because the IP address has a specified "time to live" it is very likely you will get the same IP address, especially if you are just rebooting to use your second or third HDD. The other option you have is to have a fixed IP address, and you can choose the IP you use to be different for each of the three HDDs, though the IP the rest of the world sees for your computer will still be the one assigned to the Cable or DSL modem, and subject to any changes they may make.

    If you are still on dial-up, your IP will be assigned by your service provider, and will change periodically depending on their policies and available DHCP pools.

    DHCP servers (and the app on your firewall/router) assign IP addresses from a pool of addresses. They use the physical address (MAC address) of your ethernet card, adapter or wireless connection to identify your computer. As you swap in different HDDs )and operating systems if you wish), the DHCP server will see you as the same computer because your MAC address doesn't change.

    Normally, when people ask this question it's because they want to host something on their local computers or servers and make it available to others on the internet. (Like hosting your own server instead of using someone like HostGator). If you need to have an IP address that is routable for others to connect to your server or webcams, there are services that you can use that provide the address translation needed to provide a fixed address for customers/clients and accomodate the changes in IP your service provider puts you through. Given the cost of Internet Hosting these days, it's typically not worth the hassle unless you are doing something like providing a local webcam to the world. Most service providers expressly prohibit running your own servers or similar connections unless you have a business account with a fixed IP (or more) assigned to you.

    From a command prompt, you can enter ipconfig /all and see the ip address of your computer. If you go to whatismyip.com or a similar service, you can see what IP address the world sees you at (right now). This public address will change as your service provider desires, unless you have a fixed IP business account.
    If you have your own firewall/router, the two addresses will be different, because your computer connects to your router on one address, which translates that local address to your assigned public one. With a router you can have several computers in your home, and all will appear to come from the same external IP address. What makes each one unique is a port number that allows your router to send the correct traffic to each local computer.

    change the hosting providers in the proper order.when your site is 100% functional at the new hosting provider,
    DNS records should then be updated.

    :confused:

    No. Hard drives have nothing to do with IP adresses.
