If I do not have access to the router / DHCP server to create a static reservation (i.e. asking the router / DHCP server to set aside a specific IP address when a certain MAC address requests it), how can I set my Windows 7 workstation to have a static IPv4 address?

  • Will you use the IP that DHCP already gave you? There are some strategies to choose an IP that most likely will not handed out to anyone else, or better, not at all. (choosing one high in the IP range, or one that is not within the range of the DHCP server pool. It can involce some guesswork though :) – Lexib0y Nov 5 '15 at 0:01
  • @lexib0y add any awesome information you can! – Canadian Luke Nov 5 '15 at 0:05
  • It would help if you could give the current IP address, netmask and gateway, because some educated guessing is needed :) – Lexib0y Nov 6 '15 at 12:32

  1. Click on Start, then Control Panel
  2. Choose Network and Internet -> Network and Sharing Center (or just Network and Sharing Center)
  3. Click Change Adapter Settings on the left
  4. Find the network adapter (NIC) that you are currently connecting with. Right-click it and click Properties (requires Admin access)
  5. Choose Internet Protocol version 4 (TCP/IPv4) and choose Properties enter image description here
  6. Choose the option to Use the following IP address: and fill in the blanks for your network. enter image description here
  7. Click OK, and close the next window. Verify you can access the Internet.

You will now have the IP Address always set to this address. Because it is getting set to whatever was found below, once your computers find the new address, it will remember it. Your router (more specifically, the DNS Service) will match the name with the IP Address, and HomeGroups are built to just know (using IPv6, usually).

How do you find out what you can put here?

  1. Click on Start, type cmd and press Enter to bring up the Command Prompt.
  2. Type ipconfig /all and press Enter
  3. Check for the following items:

    IPv4 Address. . . . . . . . . . . : 192.168.0.xxx
    Subnet Mask . . . . . . . . . . . : 255.255.255.0
    Default Gateway . . . . . . . . . : 192.168.0.xxx
    DNS Servers . . . . . . . . . . . : 192.168.0.xxx
    

    Your screen will output different numbers. Keep the information handy, and put them into the dialog above.

  4. Type exit and press Enter to exit.

You can also use NETSH command to do this.

Setting static IP address:

netsh interface ip set address name="network_name" static 192.168.0.1 255.255.255.0 192.168.0.254
                                                          ^ IP Address ^ Subnet Mask ^ Default Gateway

Setting Primary & Seconday DNS

netsh interface ip set dns name=”Local Area Connection” static 192.168.0.250
netsh interface ip add dns name=”Local Area Connection” 8.8.8.8 index=2
