How Do I Change My Computer Ip Address?

1. Daniel Says

   There is a source that I’ve linked to this answer that will give you the specifics about
   how to change your IP address on your Windows 7 system. But, there are many caveats.
   First, you don’t want to do anything that will cause two systems on your network to have
   the same IP address. Second, you will run into problems if you give your system and IP
   address that is outside the network that you’re on. In other words, let’s say your network
   is connected to the Internet at large through a router, and your internal network starts with
   192.168.1. and the outside network is 192.168.2.. Here, the fact
   that both networks start with 192.168 implies that if you try to set up a server on your
   system with a fixed IP address in this range, machines out on the Internet will not be able
   to reach your system as these are not routable IP addresses.
   So, let’s say you contact your network provider and ask for another IP address and let’s
   say it’s 123.45.67.89 just for grins. This IP address is routable. So you put that address into
   your system and stick it onto the internal net where all the machines with addresses starting
   with 192.168.1.x reside. All is well. Right? Wrong. The machines inside the network will
   be looking for for that network to be on the WAN side of the router, or maybe in the DMZ.
   If you set your DMZ up so that the network there starts with 123.45.67 and set up a netmask
   appropriately, then perhaps your machines inside your network will reach it, but those on the
   Internet at large will probably never see it since your WAN IP on the outside starts with 192.168.2
   which is non-routable.
   But, if your network provider provides you a range of routable IP addresses and a netmask, then you could use that for your DMZ and use the internal network for your desktops and place your server into the DMZ.
   Anyway, if you already have an IP you want to set your system to, you can get into the command window by pressing the Windows key and R and typing command, or go to Start, select Run, and type command.
   From there, you can type “ipconfig /release” without the quotes.
   Then you can click on Start and go to the Control Center and select Network and Sharing Center.
   Click on Properties and Local Area Connection. Right click on your connection and select Properties.
   Go to the General Tab and double click on Internet Protocol (IP).
   From there you should tell the system whether to get the IP automatically or hardcode it in along with a netmask. The default gateway would be the IP your system would use to reach your router–not the IP address on the outside of the router linking you to the outside. Use the inner IP that you’re connected to.
   You’ll have a chance to select your DNS server. That’s the server that will allow you to look up IP addresses using a hostname. It may be your router or a DNS server you or your company owns, or the DNS server of your Internet Service Provider.
   All in all, I would highly recommend working with your network folks in your company to make sure what you’re doing is secure because one way hackers break in is to get you to use their DNS server so they can direct your traffic through one of their systems and tap off your internet traffic among doing other things.

   Of course you can change your computers IP address. Click on Start, then Network.
   Then on the top click Network and Sharing Center.
   Once open, look to teh left and click on Change Adaptor Settings.
   Once this is open, right click on your connection (prob will say Local Connection), then click properties.
   Scroll down until you see TCP/IP and click Properties again, then change you IP address.
   Hope this helps

   See if your ISP will give you a new one. They most likely will want to know why you want to change it. Odds are they will never do it again for you (unless you paid them extra). Another option is to change to a different ISP.
