    Hi, Minus Ice. Welcome to Windows BBS! :)

    Are you talking about changing your computer's IP address on a local area network (LAN) or your IP address as seen by a wide area network (WAN) such as the Internet?

    If you're referring to your Internet IP address, that is usually assigned by your Internet Service Provider (ISP). You might not have any control over that.

    On dial-up connections, the ISP usually assigns the IP address from a pool of available IP addresses each time you dial up (which is usually a different IP address each time). I think broadband connections such as DSL or cable often do something similar although you might be able to have your ISP assign your computer a different static (non-changing) IP address.

    Thanks for the warm welcome. I tell you exactly what I do. I go to CMD, type in " ipconfig /release ", then leave and go to local area connection4, and click into properties, and then internet protocol (TCP/IP). Then I type in a bunch of random numbers in " use the following ip address ", click tab, and wait for the subnet mask and default gateway numbers to show, then click ok. Then I go back and click " obtain Ip address automatically ", click ok again, and then I have a new one. The problem is, that doesn't work anymore, and I wonder why not? Is there another way to change it?

    When you set the IP address to automatic, you set up your computer to request an IP address from a network server called DHCP. On small networks, this service is provided by your router. On larger network it is a service provided by your server.

    One of the features of DHCP, is that it will try to give out the same IP address to a computer each time it tries to connect. It will often only give a different address, if another computer has taken the address and therefore the original isn't available.

    ipconfig /release, releases the automatically assigned IP address. inconfig /renew will force your system to renegotiate an IP address with the DHCP server (more easily that the process you are using).

    If you want to be able to change your IP address ragularly, you might find it easier to manually configure the IP address. Then you can change it at will.

    Doing that only gives me the same IP address again.

    How do I do that?

    Your method is dark and mysterious and unecessary.

    Right click the network icon and click Repair.

    If you are assigned the same IP address, ask where the address is coming from. If the DHCP server is your local Network, then it is not unusual to persistently have the same IP address assigned. As it is a local IP and not used over the internet it should be of no concern.

    If the IP address is coming from your ISP's DHCP servers, then unplug the modem and wait 20 minutes. Plug it in again and reboot your machine.

    It is possible, and becoming more common, for ISPs to NAT IPs that they distribute. This is to preserve IPv4 address space. If your ISP moved in that direction your IP may well be essentially static.

    First, tell us your network setup. Do you have a broadband modem & router? If so, what brand? Or just a modem & no router? Also, post here the current ip you have now if it begins with 192.x.x.x

    Yes I do, and the brand is motorola, but it also says vonage. That's the brand of the router. The Brand of the modem is arris. And my IP address is 192.168.15.2.

    Thanks.
    OK, you are getting what is called a dynamic ip address from the router because you have chosen to "Obtain an IP address automatically" . When choiosing that, then ANY other info you typed in is overridden and not used. You must use "automatic" or eneter the info manually.

    If want to manually set a static ip address (one that never changes) then do this:
    1. open a command window and type:
    ipconfig /all
    and write down the ip address next to where it says Default Gateway.

    2. rt click My Network Places & select Properties.

    3. rt click Local Area Connection & select Properties.

    4. double click on TCP/IP Internet protocol in the list.

    5. click on Use the Following IP Address.

    6. enter the ip address. ( SEE #11 BELOW)

    7. subnet mask will fill in by itself.

    8. enter default gateway ip address.

    9. click on Use the following DNS servers

    10. preferred DNS server enter same ip address as default gateway.

    11. IP - It must be greater than the IP address value of the voice gateway. For example, if the IP address of the voice gateway is 192.168.15.1 (default), the starting IP address must be 192.168.15.2 (or higher).

    This is probably your manual:

    Tony, thanks for the help. Don't I have a static IP address already? Isn't that why it doesn't change? I thought that was what static was, and dynamic the total opposite.

    Per what you said earlier about clicking "obtain ip address automatically" then NO, you do not have a static ip address, you have a dynamic ip address. The router will try to assign you the same ip address again & again as long as no other comp on the network uses that ip address, but eventually the router will assign a different address. When using a dynamic ip (obtain automatically), the router handles addressing, when using static ip (use following ip) then YOU handle addressing, not the router.

    You can't just enter random numbers for a static ip address, subnet, gateway & dns server. You must follow steps 1-11 above paying particular attention to 11.

    Tony, I don't want to keep it the same forever. I want to change it manually, and anytime at will, like reggie was talking about.

    I understand that.
    So, follow my steps above to set a static ip. Then repeat them when you want to change it again. You have no real control over what ip you get UNLESS you setup a static ip.

    If you setup a dynamic ip ( "obtain IP address automatically ") then you can NEVER choose what IP the router will assign you.

    Either YOU set the static IP per my steps above or the ROUTER sets the IP dynamically. No other way to do it.

    Tony - I just had a friend check it out to see if it worked, and it didn't. He still says it shows up the same - He runs a football website, and says my IP still shows up the same on his site. I did everything you said, and still nothing.

    And he is correct because he is seeing you WAN ip address, not your LAN ip address! You cannot change your WAN ip address, you have no control over that, it is controlled by your isp.

    The isp assigns an address, the router gets this address and the router in turn assign ip adresses to computers connected to it OR the computers assign their own local ip addresses.

    You may not fully understand ip addressing. There are basically 2 types of addresses to consider, WAN addresses & LAN addresses. WAN = Wide Area Network & LAN = Local Area Network.

    WAN addresses are public & unique, LAN addresses are private and unique ONLY on that LAN. There are millions of computers with the private address of 192.168.1.100. There can be only one computer with a public address ogf xx.xx.xx.xx.

    Certain ip addreses are called reserved, such as the group of 192.168.xx.xx addresses, these can only be used for private addresses on a LAN. There are other private groups as well.

    Your friend is seeing your public isp assigned ip address, you cannot change that nor do you have control over it. Go here & see:
    www.turrisi.org/visitor-info.php

    Your browser, or any other Internet program you use sends the public ip address inside packets of data when it communicates to other computers on the Internet. This is absolutely necessary in order for TCP/IP to work. Take note of that name, TCP/IP, which means Transmission Control Protocol/Internet Protocol. We are talking about Internet Protocol (IP) Addresses.

    The ONLY way to completely hide your ip address is to connect to the Internet using what is called a proxy server. Once connected, the proxy server public ip address is sent in the transmissions instead of your public ip address.

    Since you have a router, you are dealing with two IP addresses.

    One is the local IP assigned to your computer by the router. It's only used by the router and any other computers on your local network (connected to the same router).

    The IP addess seen by the world/internet is assigned to you by your ISP. Only they can change it. Some ISPs use dynamic IPs...the address your router gets when it connects to your ISPs servers is whatever number is available at the time. Some use static IPs...a unique number assigned to your account so it never changes.

    Tony - That's too bad, because the method I used previously used to work, until I got the router. I was assigned a new IP every time I did that, and it would show differently on a site everytime.

    Many routers have a "MAC Cloning" feature, intended for use in Cable systems that use MAC-based authentication.

    I have never seen an ADSL system use the MAC address for authentication, but anything is possible.
